Born in Bridgeport, Connecticut, Mayer moved to Atlanta, Georgia and began playing in local clubs in 1998.  He released the extended play "Inside Wants Out" in September of the following year.  "Inside Wants Out", as well as continued performances, brought Mayer to the attention of independent record label Aware Records.  Aware later signed Mayer and released his full-length debut studio album, "Room for Squares", in June 2001.  When Columbia Records acquired Aware, the album was re-released in September and promoted as a major label release.  Following its re-release, "Room for Squares" peaked at number eight on the United States "Billboard" 200.  The album has since sold over four million copies in the United States, and was certified four times platinum by the Recording Industry Association of America (RIAA).

" Heavier Things", Mayer's second studio album, was released in September 2003.  It topped the "Billboard" 200 and attained a double platinum certification from the RIAA.

He is best known for his work with the English rock band Radiohead, having produced all of their studio albums since "OK Computer" (1997); he has been dubbed the "sixth member" of the band, in an allusion to George Martin being called the "Fifth Beatle".  Godrich has also worked extensively with Radiohead singer Thom Yorke on his solo material, and is a member of the bands Atoms for Peace (with Yorke) and Ultraísta.  Other acts Godrich has worked with include Beck, Paul McCartney, U2, R.E.M. and Roger Waters.  He is the creator of the music webseries "From the Basement".

Alkaline Trio: Alkaline Trio is an American alternative rock band from McHenry, Illinois.  The band consists of guitarist and vocalist Matt Skiba, bassist and vocalist Dan Andriano, and drummer Derek Grant.  Founded in late 1996 by Skiba, bassist Rob Doran, and drummer Glenn Porter, Alkaline Trio released its debut single, "Sundials", in 1997.  Following its release, Doran departed from the band and was replaced by Andriano.  The band subsequently recorded an EP, "For Your Lungs Only" (1998), and its debut studio album, "Goddamnit" (1998).  Following the release of the band's second album, "Maybe I'll Catch Fire" (2000), Porter left the band and was replaced by Mike Felumlee for its subsequent album, "From Here to Infirmary" (2001).

Wah Wah (album): Wah Wah is the sixth studio album by the Manchester-based English indie rock band James.  After the success of their fourth album, "Seven" (1992), the band entered Real World Studios, Box, Wiltshire, to record their fifth album "Laid" in early 1993 with producer Brian Eno, who the group had longed to work with.  Prior to recording "Laid", Eno observed the band's jam sessions at their Manchester rehearsal room, and considered these improvised pieces to be as important to the band's music as their eventually crafted songs.  He requested to the group that whilst they were recording "Laid", they would also concurrently record an album of their improvisations which Eno and, by Eno's request, second producer Markus Dravs would produce in a secondary studio in the Real World complex.  Each composition started off with the band's improvisation being recorded, which Dravs would then edit, generally alone whilst James and Eno were recording "Laid".  Eno and Dravs would take a "promising" part of a recording and then mixed them only once.  Tim Booth's desire to re-record some of his vocals caused friction in the studio.

Train discography: American pop rock band Train has released ten studio albums, two live albums, one video album, four extended plays, 30 singles, four promotional singles, and 26 music videos.  The band independently released their eponymous debut studio album in 1996, two years after their formation.

The album peaked at number 76 on the US "Billboard" 200 and was certified platinum by the Recording Industry Association of America (RIAA).  In the period following the release of "Train", producer Brendan O'Brien started working with the band in a partnership that would last for three albums.  The band released their second studio album "Drops of Jupiter" in March 2001; it was preceded by the release of its lead single, "Drops of Jupiter (Tell Me)".  The single became a commercial success, peaking at number five on the US "Billboard" Hot 100 and also becoming a top ten hit in Australia, the Netherlands and the United Kingdom.  "Drops of Jupiter (Tell Me)" also won an award for Best Rock Song at the 44th Grammy Awards.  The album peaked at number six on the "Billboard" 200, earning a double platinum certification from the RIAA.

Operation Phoenix (album): Operation Phoenix is the fourth album by the Santa Cruz, California-based hardcore punk band Good Riddance, released May 4, 1999 through Fat Wreck Chords.  It marked a change in recording location and production team for the band: their previous three albums had been recorded in San Francisco with producer and recording engineer Ryan Greene, but for "Operation Phoenix" the band traveled to Fort Collins, Colorado to record at The Blasting Room with Jason Livermore and Descendents/All members Bill Stevenson and Stephen Egerton.  This marked the beginning of a long-term working relationship: Good Riddance would record all of their studio material at The Blasting Room using the same production team until 2003, when the band slipped into inactivity and singer Russ Rankin started Only Crime with Stevenson.  Stevenson and Livermore would return to record and produce Good Riddance's final studio album "My Republic" in 2006, which was recorded in San Francisco.  Rankin later commented that working with The Blasting Room team was a major turning point in recording for the band:

Room on Fire: Room on Fire is the second studio album by American rock band the Strokes.  It was released on October 28, 2003, by RCA Records.  The album is a follow-up to 2001's "Is This It".  Three singles were released from the album: "", "Reptilia", and "The End Has No End".  Grammy-winning producer Nigel Godrich was initially in charge of production, but the Strokes felt he made the songs seem "soulless".  The band went back to work with "Is This It" producer Gordon Raphael.  The album features a slightly smoother sound than its predecessor.  The bass guitar is less present except for several moments when it becomes the focal point of the song.  The album title "Room on Fire" was drawn from a line in "Reptilia": "The room is on fire as she's fixing her hair."  "Room on Fire" received positive reviews upon release.  It reached number two on the UK Albums Chart and debuted at number four in the US on the "Billboard" 200, where it went on to sell 597,000 units by October 2006 and was certified Gold.

Chimaira released a self-titled album in August 2005, which peaked at number 74 on the "Billboard" 200.  After an internal crisis due to pressure from the label by a new release, the band moved on from Roadrunner and signed a new deal with Ferret Music.
