Question: Who was a producer, Lou Reed or John Rzeznik?
Context: John Joseph Theodore Rzeznik ( ; born December 5, 1965) is an American musician, singer-songwriter, and producer.  He is best known as the guitarist and frontman of the rock band the Goo Goo Dolls, of which he is a founding member and with whom he has recorded eleven studio albums. Lou Reed is the debut solo album by musician Lou Reed, released in 1972 by RCA Records two years after he left The Velvet Underground.  The album comprises eight new recordings of then-unreleased Velvet Underground songs, plus two new songs, "Going Down" and "Berlin" (the latter was re-recorded by Reed as the title track for his 1973 album "Berlin").  Reed was backed by London session musicians, two of whom, Rick Wakeman and Steve Howe, were from the progressive rock band Yes.  Wakeman recalled that during the session at Morgan Studios, "the lights had to be out so nobody could see." Let Us Now Praise Famous Death Dwarves (or how I slugged it out with Lou Reed and stayed awake) is an infamous interview with Lou Reed conducted by Lester Bangs and published in "Creem" magazine in 1975.  It is now regarded as a classic document of music journalism.  The title is a play on "Let Us Now Praise Famous Men," the book by James Agee.  The full interview was reprinted in the New Musical Express in November 2013, as a tribute to Lou Reed, who died the previous month. Something for the Rest of Us is the ninth studio album by American rock band Goo Goo Dolls.  It was released on August 28, 2010 in Australia and on August 31 in North America through Warner Bros.  Records.  The recording process took place during the spring to fall of 2009 in the GCR Audio studio in Buffalo and Paramount Studios as well as "the Ark" in Los Angeles, with producer Tim Palmer.  A single had been originally slated to be released in November 2009 with an album release in February 2010, but the band went back into the studio in January 2010.  According to lead singer and guitarist John Rzeznik, this was done to make further improvements on what they had previously thought had been a finished record.  Several producers were brought in to assist on the production process, including Butch Vig, John Fields, Paul David Hager and Rob Cavallo.  "Something for the Rest of Us" is the third Goo Goo Dolls studio album that Cavallo has produced ("Dizzy Up the Girl" and "Gutterflower").  When asked about the length of time between albums, Rzeznik admitted it was a mix of songwriting issues as well as taking time out for personal reasons; "I wanted to really dig deep and there are a million songs I threw away, like, “Nah, it's not good enough.  I wanna do something different.  I wanna do something better, go deeper.  I also wanted to have a life with my girlfriend for a while.  I owed it to her to spend some time with her and be normal and be in one place.  That was kind of important."  In one of the Ustream sessions, Robby revealed that the album would have twelve songs and "Real" is not among them.  In late May, John announced that "Home" would be the first single and was released onto radio and iTunes stores on June 8, 2010. The Essential Lou Reed is a compilation album by Lou Reed released in 2011 by RCA Records.  The album features classic Lou Reed solo work and songs from his band the Velvet Underground. Jed is the second studio album by American rock band Goo Goo Dolls.  It is the first studio album in which John Rzeznik sang vocals for some of the tracks.  The majority of the songs are sung by Robby Takac, with Rzeznik taking over for two ("Up Yours" and "James Dean").  Fellow Western New York native Lance Diamond sings vocals on track seven, "Down On The Corner."  The second track on the album, "Up Yours", was the only song from "Jed" found on the band's compilation album "What I Learned About Ego, Opinion, Art & Commerce".  The song "No Way Out" was also included on the band's most recent compilation album "Volume Two", which consisted of other album tracks, b-sides and rarities.  The album was re-released on CD on February 22, 1994. "I'm Still Here (Jim's Theme)" is a song written by the Goo Goo Dolls frontman John Rzeznik for Disney's animated film "Treasure Planet".  The song is in the key of A Major and was released by Rzeznik as a single away from The Goo Goo Dolls.  It was a moderately successful pop hit. Sally Can't Dance is the fourth solo album by Lou Reed.  It remains Reed's highest-charting album, having peaked at #10 during a fourteen-week stay on the "Billboard" album chart in October 1974.  It is also the first solo Lou Reed album not to feature any songs originally recorded by Reed's earlier band, the Velvet Underground, as well as the first of Reed's solo studio albums to be recorded in the United States (Reed's previous three albums were all recorded in the United Kingdom). The Creation of the Universe is an album by Lou Reed's Metal Machine Trio.  The trio was formed in 2008 with Ulrich Krieger and Sarth Calhoun to play music inspired by Reed's 1975 album "Metal Machine Music".  The first concerts of the group were on October 2 and 3, 2008, at REDCAT in Los Angeles.  The group was named Metal Machine Trio only after these concerts.  The concert itself was announced as Lou Reed and Ulrich Krieger: Unclassified.  The CD is the unedited live recording of both nights.  It is available in a variety of formats from Lou Reed's website including, MP3, FLAC, 2 Disk CD and Deluxe CD.  Cover and inlay photos are by Lou Reed. Lewis Allan Reed (March 2, 1942 – October 27, 2013) was an American musician, singer and songwriter.  He was the guitarist, vocalist, and principal songwriter of the Velvet Underground, and his solo career spanned five decades.  The Velvet Underground had little success during their active years, but later gained a significant cult following to become one of the most widely acclaimed and influential bands in rock history.  Brian Eno famously stated that, while the Velvet Underground's debut album sold only 30,000 copies, "everyone who bought one of those 30,000 copies started a band".
