Home Is Such a Lonely Place: "Home Is Such a Lonely Place" is a song recorded by American rock band Blink-182 for the group's seventh studio album, "California" (2016).  The song was released as the third single from "California" on April 18, 2017 through BMG.  It is a ballad with a finger-picked guitar and strings.  Lyrically, the song revolves around the idea of letting go of the ones you love.  Bassist Mark Hoppus and producer John Feldmann first began developing the song while discussing their families, and how tough it might be when their children grow up and leave home.  The song was written by Hoppus, Feldmann, drummer Travis Barker, guitarist Matt Skiba, and songwriter David Hodges.

Blink-182: Blink-182 (often stylized as blink-182; pronounced "blink one eighty two") is an American rock band formed in Poway, California in 1992.  Since 2015, the lineup of the band has consisted of bassist and vocalist Mark Hoppus, drummer Travis Barker, and guitarist and vocalist Matt Skiba.  Founded by guitarist and vocalist Tom DeLonge, Hoppus and drummer Scott Raynor, the band emerged from the Southern California punk scene of the early 1990s and first gained notoriety for high-energy live shows and irreverent lyrical toilet humor.  Blink-182 was initially known as Blink until an Irish band of the same name threatened legal action; in response, the band appended the meaningless number "-182".

Buddha (album): Buddha is the third and final demo by the American rock band Blink-182.  Recorded and released in January 1994 under the name Blink, it was the band's first recording to be sold and distributed.  Blink-182 was formed in Poway, California, a suburb outside of San Diego, in August 1992.  Guitarist Tom DeLonge and Mark Hoppus were introduced to one another by Hoppus' sister.  The duo recruited drummer Scott Raynor and began to practice together in his bedroom, spending hours together writing music, attending punk shows and movies and playing practical jokes.  The band had recorded two previous demos in Raynor's bedroom — "Flyswatter" and "Demo No.2" — using a four track recorder.  Most of the tracks from the demo were re-recorded for their debut album "Cheshire Cat".

Commit This to Memory: Commit This to Memory is the second studio album by American rock band Motion City Soundtrack.

Tensions had risen in the group and guitarist Tom DeLonge desired to take time off.  Bassist Mark Hoppus and Travis Barker argued with DeLonge regarding the band's future and their possible next album, and heated exchanges led to DeLonge's exit.
