Probot
Probot was a heavy metal side project of ex-Nirvana drummer and Foo Fighters rhythm guitarist and lead-singer Dave Grohl. Described by Grohl as "a death metal "Supernatural"", the album mixes instrumentals recorded by Grohl himself with various metal singers whom the musician admired. The album was released in February 2004 by Southern Lord Records. It featured one single entitled "Centuries of Sin"/"The Emerald Law". Background. After years of popularity in the alternative rock scene, Dave Grohl wanted to express the passion for heavy metal he bore since his youth. He mentioned the catalyst of the experience being  during the first leg of the tour in support of the Foo Fighters album "There Is Nothing Left to Lose", with the mellower songs making him think about the heavier bands he used to listen to. Following the tour, Grohl went to his house in Alexandria, Virginia, to record some heavier songs in his home studio Studio 606 with Adam Kasper. Grohl would play with his Gibson Explorer as he watched TV with Kasper, and once he got a riff that interested him, he would bring Kasper along to the basement, recording a drum arrangement followed by bass and guitar . Each instrumental would take about 45 minutes to complete. Grohl said that he did not intend to make an album out of the recordings – "I didn’t even call them songs because they were bare instrumentals with no intention of putting vocals on them and no direction as an actual song." After four days of recording, Grohl and Kasper had done seven tracks, with Grohl making some copies out of the master tape before labeling it Probot to distinguish from the Foo Fighters' work. Some time later, inspired by the Santana album "Supernatural", Grohl decided to attempt collaborations with singers  he had idolized. He came up with "my wish list of all of my favorite singers from this era which is '82 to '89 underground metal, and all the bands I listened to at the time: Eric Wagner from Trouble, Snake from Voivod, Cronos [from Venom], Lemmy and Wino," and started contacting the musicians, some of whom were reached by Grohl's friend Matt Sweeney given the Foo Fighters had restarted their tour. Grohl feared his fame built out of being "a stupid, middle-of-the-road, alternative-rock idiot" could drive the metal singers away, but many agreed immediately . Cronos would later explain that "I'm open for everything. And Dave's cool," detailing that Grohl's email opened with "a real fan letter" where he mentioned his longtime appreciation of Venom, and then explained about his idea of a metal album with all his metal heroes "to get something off his chest." Seeing the positive response, Grohl brought Kasper and Sweeney back to do five more instrumental tracks and round out the project. According to Grohl, the songs sent to Eric Wagner and King Diamond had been previously done for Ozzy Osbourne as he was contacted to write  for the then-upcoming "Down to Earth", but when Osbourne's label did not respond, he repurposed them for Probot. Sweeney would organize the project as Grohl toured with the Foo Fighters, getting vocalists on board and organizing tracks. Then the demo tapes were sent to the singers, each of whom was asked to come up with lyrics, record them and then title the song. Cronos detailed he wrote three different versions so Grohl could choose one. Production and style. On the album, Grohl teamed up with heavy metal vocalists from 1980s and 1990s bands who influenced his musical tastes  while he was growing up. Similar to 1995's "Foo Fighters", Grohl wrote all of the music and performed most of the instrumentation. Each track on the album features a different lead singer including Lemmy, Max Cavalera, King Diamond and Tom Warrior. Grohl described the sequencing as "like a compilation tape that I would have made as a kid." Only Lemmy and Wino visited Studio 606 to record, with all the others sending tapes from studio to studio until the album was finished. Soundgarden guitarist Kim Thayil plays additional guitar on two tracks thanks to Kasper, who had brought the  Probot tapes to Seattle and they attracted Thayil's interest. Grohl was pleased with the addition as Thayil had more experience with lead guitars, while Grohl was "more about the riff and the rhythm". A bonus track titled "I Am The Warlock" was provided by comedian/actor/musician Jack Black. According to Black, who described the song as "a homage to 'Iron Man.'" after Grohl approached him regarding writing lyrics, his spouse Tanya Haden suggested "it should be about a fucked up relationship," so Black made it about a warlock. Grohl also approached death metal legend Chuck Schuldiner of Death  to contribute to Probot. However, Schuldiner was struggling with brain cancer and was unable to be involved despite the efforts of Grohl and others to raise funds for his medical treatment. Grohl also attempted to get Slayer's lead singer Tom Araya on the album, but he was unable due to scheduling conflicts. To replace him, Grohl invited Kurt Brecht from D.R.I. Grohl mentioned he and Sweeney had discussed and considered a lot of different singers, including the retired Jeff Becerra of Possessed, Chuck Billy from Testament, Pantera's Phil Anselmo, and the vocalists from Kreator, Destruction, Hirax and Candlemass . Sweeney vetoed Unleashed's Johnny Hedlund, who at the time was rumored to be a Nazi sympathizer. In a 2007 interview for "Guitar World" magazine, Grohl was asked about the future of Probot. He explained that the idea behind Probot was to choose his favorite vocalists that inspired him when he was a teenager. Grohl said that he does not think that he will do it again, because he does not want to go outside of that idea. Release. Despite Grohl's label Roswell having a deal with RCA Records, he knew such an unorthodox project featuring cult musicians of  the past would not be easily accepted by major labels. RCA was interested at first, but later Grohl decided to follow the spirit of the original bands "on independent, punk-rock do it yourself labels." So Grohl's friend Pete Stahl, with whom he had played in Scream and was then in the band Goatsnake, suggested the label of his bandmate Greg Anderson, the smaller metal-based Southern Lord Records. The album is available as a single CD and a double LP (available on red and black vinyl). Southern Lord released a double A-sided single, "Centuries of Sin/The  Emerald Law" in a limited edition of 6,666 on 7" vinyl only. It is available on black, green, red & red/black swirl vinyl, and sold out shortly after release. The album artwork was created by musician Away (Michel Langevin) of Voivod. Reception. Critical reception to the Probot album was largely positive with few recurring complaints; Metacritic shows a 72/100 critic rating based on 21 reviews. "Rolling Stone" declared it as "the year's first great metal album," while "Blender" reported, "Unlike similar records... this has a unity of aesthetic purpose, a competitive wallop, even (kind of) a seriousness." David Browne  of "Entertainment Weekly" gave "Probot" a B− rating. He notes, "For a lark, it aims for (and hits) a few bull's-eyes, including the whiplashing 'The Emerald Law' and the post-apocalyptic death march 'Ice Cold Man'." However, Browne comments how the mystery and thrill of vintage metal bands is "largely gone" with many lyrics on "Probot" sounding "more amusing than menacing" and even "unintentionally funny." He sums it up as "lying somewhere between homage and howler." "Probot" earned an A rating in "Stylus" magazine as well as the title of StylusMagazine.com's Album of the Week for February 8–14 , 2004. Scott McKeating's extensive review describes how "Probot balances the grit with the sonic polish without lapsing into Metallica's "Metallica". This is metal that demands banging, shaking and stamping." He commends the ambition of its overall conception, noting, "Very few [artists] go as far as Grohl and actually create something vital and new in their mid-thirties from their teenage obsessions. . . "Probot" is an inspirational record in every sense." Adrien Begrand of PopMatters describes it as "One of the coolest ideas for an album in a long time, Grohl has put together a record that not only serves  as a sincere tribute to the metal and hardcore bands of his youth, but features all his favorite vocalists as well." He gave a favorable review but heavily discussed Grohl's guitar skills and songwriting as lacking: "The biggest problem on the album is Grohl's complete lack of inventiveness as a guitar player. . . Had Dave Grohl used more guest musicians instead of trying to do everything himself, "Probot" would have been much better." Despite these criticisms, Begrand considers it "impossible not to like this album, mistakes and all." Awarding a 4/5 rating, Allmusic's Alex Henderson emphasizes the wide  variety of genres featured on "Probot" and adds, "Whatever the style of metal that he is embracing, Grohl's drumming is passionate throughout this fine album, which is as rewarding as it is unpredictable." Section::::"Shake Your Blood". Although Grohl recorded the guitar and drums himself, Lemmy performed his own bass and wrote the lyrics to "Shake Your Blood". He noted, "I wrote the lyrics in about ten minutes. . . It's rock & roll, you know. It's not one of those complicated things." The song bears strong resemblance to Lemmy's style and was considered "a terrific Motörhead clone" by Adrien  Begrand of PopMatters. The "Shake Your Blood" music video was filmed in November 2003 and released shortly thereafter. It features an appearance by 66 women from the SuicideGirls adult entertainment website. The music video also appears on the extras section on the movie SuicideGirls: The First Tour. In the video, the band is represented with Dave Grohl on drums, Lemmy on lead vocals and bass, and Wino (who sang on the Probot track "The Emerald Law") on lead guitar. Lemmy regarded the performance as "just like a tour in the '60s, when things were a lot more fun." Live performances . Foo Fighters performed "Shake Your Blood" live with Lemmy at their 2006 Hyde Park (UK) show, and on June 18, 2011, at Foo Fighters concert in Berlin. "My Tortured Soul" was performed live on "Headbangers' Ball" in 2004, with Eric Wagner on lead vocals, Grohl on drums, Wino on lead guitar, Greg Anderson (of Goatsnake and Sunn O) on rhythm guitar, and Foo Fighters producer Nick Raskulinecz on bass guitar. This performance is available on the compilation album "MTV2 Headbangers Ball, Vol. 2". Soulfly has also been known to play "Red War" live as recently as 2009. "Ice Cold Man  has also been played by Cathedral on their 2004 tour. Centuries of Sin" has also been played by Venom on their 2009 tour in South America.
