Problem: Steven Van Zandt (born November 22, 1950) is an American musician and actor, who frequently goes by the stage names Little Steven or Miami Steve. He is a member of Bruce Springsteen's E Street Band, in which he plays guitar and mandolin. He is also known for his roles on television dramas such as Silvio Dante on The Sopranos (1999-2007) and Frank Tagliano / Giovanni "Johnny" Henriksen on Lilyhammer (2012-2014). Van Zandt also has had his own solo band called Little Steven and The Disciples of Soul, active on and off since the 1980s.

Van Zandt became a songwriter and producer for fellow Jersey shore act Southside Johnny and the Asbury Jukes in 1974, penning their signature song "I Don't Want to Go Home", co-writing other songs for them with Springsteen, and producing their most-acclaimed record, Hearts of Stone. As such, Van Zandt became a key contributor to the Jersey Shore sound. He also produced two Gary U.S. Bonds' albums. Van Zandt then went on to share production credits on the classic Springsteen albums The River and Born in the U.S.A. The first Springsteen song he co-produced was "Hungry Heart." In 1989, Jackson Browne covered the 1983 Van Zandt composition "I Am A Patriot" on his World in Motion album. Van Zandt has produced a number of other records, including an uncredited effort on the Iron City Houserockers' Have A Good Time (But Get Out Alive). Less successful was his work on Lone Justice's second album Shelter, which was a career-ending flop for the Los Angeles cowpunk band. In 1989, Van Zandt wrote "While You Were Looking at Me" for Michael Monroe's album Not Fakin' It and co-wrote videohits "Dead, Jail or Rock'n Roll" and "Smoke Screen". He was an arranger and backing vocalist for a few songs on the album. In 1992, he produced Austin TX-based Arc Angels' debut album. In 1991 Van Zandt produced a successful album, Spirit of Love, for Nigerian superstar and raggae icon, Majek Fashek. In 1993, Van Zandt wrote and produced "All Alone on Christmas" for the soundtrack of the Chris Columbus film Home Alone 2: Lost in New York, which yielded singer Darlene Love her first hit since "A Fine, Fine Boy" from 1963, thirty-one years earlier. In 1994, Van Zandt produced the eponymous debut album of the punk rock band Demolition 23 which featured ex-Hanoi Rocks members Michael Monroe and Sami Yaffa. Van Zandt also co-wrote six songs for the album with Monroe and Jude Wilder. In 1995, Van Zandt aided Meat Loaf with the song "Amnesty Is Granted" off of his Welcome to the Neighborhood album. In 2004, he contributed the song "Baby Please Don't Go" to Nancy Sinatra's self-titled album.

Question:
Testament is an American thrash metal band from Berkeley, California. Formed in 1983 under the name Legacy, the band's current lineup comprises guitarists Eric Peterson and Alex Skolnick, lead vocalist Chuck Billy, drummer Gene Hoglan, and bassist Steve Di Giorgio. Since its inception, Testament has had numerous lineup changes, leaving Peterson as the only constant member. Billy replaced original singer Steve "Zetro" Souza (who left the band to join Exodus as the replacement of Paul Baloff) in 1986, prior to the recording of their first studio album, The Legacy, and has been a member of the band since.
As early as 2009, Testament commenced writing new material for their tenth album. In an interview with Metalheadz, guitarist Eric Peterson stated that there were about four songs written and that "there's other guys in the band who like to play the more rock melodic style but the next one is gonna be a bit heavier." In a January 2011 interview during the 70000 Tons of Metal cruise, frontman Chuck Billy revealed that Testament had been working on six new songs, with four or five "maybe left to write," and would begin recording their new album by early March. On 18 May 2011, guitarist Alex Skolnick posted an update on his Twitter, saying, "Another tune done! My riffs from last week [plus] some of [fellow Testament guitarist Eric Peterson's plus] new ones we wrote today. Planning one more, then we've got more than we need." Testament began recording their tenth studio album on June 20, 2011. Drummer Paul Bostaph was unable to take part in the recording due to a "serious injury", although he was expected to rejoin when the band tours to support the album. Gene Hoglan, who played drums on the band's 1997 album Demonic, filled in for Bostaph. It was also reported that Lamb of God drummer Chris Adler would make a special guest appearance on a couple of bonus tracks. Testament appeared at the California dates of the summer 2011 Rockstar Energy Drink Mayhem Festival, replacing In Flames. On 14 July 2011, it was announced that the tenth Testament studio album would be called Dark Roots of Earth, which, after many delays, was released on July 27, 2012. Dark Roots of Earth debuted at No. 12 on Billboard 200, the band's highest chart position to date. Prior to the album's release, the band toured in the fall of 2011 with Anthrax and Death Angel. Overkill was invited to the tour, but due to the pre-production of their sixteenth studio album The Electric Age, they did not participate. It was announced on 1 December 2011 that Paul Bostaph had left Testament. Gene Hoglan recorded the drum tracks for Dark Roots of Earth and continues to play live with the band. In interviews, Testament have expressed pleasure in Hoglan's playing, and hope that he would continue playing with the band for the foreseeable future.
