Lifehouse is an American rock band from Los Angeles, California composed of Jason Wade (lead vocals, rhythm guitar, piano), Rick Woolstenhulme Jr. (drums, percussion), Bryce Soderberg (bass, vocals), and Steve Stout (lead guitar). The band came to mainstream prominence with their 2000 single "Hanging by a Moment," which led their debut studio album, No Name Face (2000). The song peaked at number two on the Billboard Hot 100, won a Billboard Music Award for Hot 100 Single of the Year—having spent 20 weeks within the top ten and over a cumulative year on the chart—and was named the best-performing single of 2001 despite not reaching the top position, making it the fourth song in the chart's history to do so.

The band has released six subsequent albums — Stanley Climbfall (2002), their eponymous third album (2005), Who We Are (2007), Smoke and Mirrors (2010), Almería (2012), and Out of the Wasteland (2015). Each were met with similar albeit trailing commercial success, spawning the singles "You and Me," "First Time," and "Whatever It Takes" — each became hits on the Mainstream Top 40, Adult Top 40, and Adult Contemporary charts, as well as the Billboard Hot 100. Lifehouse is exemplary of the adult contemporary format, meaning the band's songs are often played at public, family-oriented retail venues including supermarkets, convention centers, and malls.

Jason Wade had been writing songs as a coping mechanism since his parents' divorce. After moving to Los Angeles in 1995, he met bassist Sergio Andrade, his next-door neighbor. The following year, Wade, Andrade, and Jon "Diff" Palmer formed Blyss, the forerunner of Lifehouse, and began to play live shows at high schools and colleges. Later, Collin Hayden and Aaron Lord were added to the band.

Soon thereafter, word-of-mouth reached producer Ron Aniello, who introduced Jason to Jude Cole, who in turn introduced him to DreamWorks Records principal Michael Ostin. In 1998, Aniello produced Blyss's first demos, with the financial backing of DreamWorks Records. Some of these recordings would form the 1999 EP Diff's Lucky Day, which would be sold at live concerts or distributed among friends and music industry contacts.

In 2000, Blyss re-recorded, remixed, and released 12 of the 15 Diff's Lucky Day session demos as No Name Face, their debut major label release under the name of Lifehouse. On their choosing the band name, frontman Jason Wade said, "It's about what we do as a band and for me personally. Most of this record is about my life and about life's circumstances. Not only my life, but other people's lives. We thought Lifehouse was a good name for it."

No Name Face met significant commercial success and established the band, and eventually would sell in excess of four million copies worldwide. This was in part due to the success of "Hanging by a Moment", Lifehouse's first commercial single. Due to the charisma and talent of frontman Wade, DreamWorks Records' focus was primarily on him. "Hanging by a Moment" was the third song in chart history to be named the "No. 1 Song of the Year" on the Billboard Hot 100 despite not having reached No. 1 on any weekly Billboard Hot 100 survey (after Sam the Sham & The Pharaohs' "Wooly Bully" in 1965 and Faith Hill's "Breathe" in 2000).^{[citation needed]} The second single from the album, "Sick Cycle Carousel", was not as commercially successful as "Hanging by a Moment", peaking at No. 21 on the Billboard Modern Rock chart; the third and final single was "Breathing", a reworking of a song featured on Diff's Lucky Day.^{[citation needed]}

The song "Everything" was the first of many Lifehouse songs to be featured in The WB's future hit series Smallville. It was used in the series pilot and season 1 finale, and again in the series' 200th episode "Homecoming" in the show's 10th and final season, as an homage to its season 1 episodes nine years prior. The song "You and Me" from the band's eponymous third album would be released on Smallville's second soundtrack, Smallville: The Metropolis Mix, in an extended form subtitled "You and Me (Wedding Version)", and the band itself would perform the song live as a special guest appearance in the school prom scene at the end of the season 4 episode "Spirit". Seven of the band's songs would be featured in episodes of the series' first four seasons.

The song "Somewhere in Between", also from No Name Face, was featured in the first-season episode of Falcon Beach, "The Blame Game".
