From First to Last is an American post-hardcore band based in Los Angeles Area and Tampa, Florida. The current line-up consists of lead vocalist and multi-instrumentalist Sonny Moore, lead guitarist Matt Good, rhythm guitarist Travis Richter, bassist Matt Manning, and drummer Derek Bloom. The band released their first EP titled Aesthetic in 2003 which they recorded with founding member and vocalist Phillip Reardon who left the band in 2004 due to personal and creative differences.

The band went to Radio Star Studios in Weed, California to record their second album, produced by Ross Robinson. As their previous bassist Weisberg had been formally asked to leave the band due to internal conflicts, producer Ross Robinson asked Wes Borland, former Limp Bizkit guitarist, to play bass on the album. Borland later played several tours with the band. The album was released on March 21, 2006. It opened on the Billboard albums chart at No. 25, with first-week sales of over 33,000. Shortly thereafter in April, they signed to major label Capitol Records after bidding between that label and Warner Bros..  From mid March to mid May the band toured alongside Fall Out Boy, Hawthorne Heights and The All-American Rejects for the "Black Clouds and Underdogs Tour" in support of their release Heroine.  FFTL then did a short European Tour with various bands. The band then played several dates on the 2006 Vans Warped Tour, but were forced to drop out due to surgical removal of a nodule on Moore's vocal cords. He received his second nodule surgery in early July (his first being in May 2005). Following his recovery, From First to Last went out on the "World Championship Tour" supporting Atreyu along with Every Time I Die and Chiodos. While on that tour, Moore once again had vocal cord problems and had to leave the tour. The band had planned to have guitarists Good and Richter cover Moore's vocal duties for the duration of the tour until singer of Chiodos, Craig Owens, insisted that he provide lead vocals for their sets. Atreyu eventually forced From First to Last to drop the tour. The band later explained, "Our plan to enable us to play the rest of the tour was disregarded and as our crew was setting up for the show in Worcester, MA we were informed that we were being kicked off of the tour. Understand that it was not our choice to leave this tour... we were forced to leave." Atreyu then returned a statement about the controversy concerning From First to Last's departure, saying, "They couldn't perform as FFTL and are no longer on this tour."  Borland toured with From First To Last roughly since early 2006. He announced plans for a Fall 2006 tour that never went through due to Black Light Burns needing to find a new record label after Borland left Geffen Records. Borland has discussed plans to write and perform on the next From First To Last album, but he left the band due to Black Light Burns' busy schedule started to pick up, leaving no room for work with From First to Last.
