Jejune formed in the mid-'90s at Berklee College of Music in Boston, Massachusetts. The band has been commonly identified with the emo genre, particularly the late-'90s indie-emo scene. The three founding members -- Arabella Harrison (bass/vocals), Joey Guevara (guitar/vocals) and Chris Vanacore (drums) -- met while studying at the college. The band relocated to San Diego in 1997.
Many of Jejune's songs fit the construct and sensibilities of the emotional hardcore genre (aka emo). Intimate verses of melodic, melancholic reflection ascend to choruses of extreme musical and emotional intensity (a comparative blitz of noise.) Among similar bands of the time, Jejune's use of blended male/female vocals and pop sensibility helped to make them stand out.
The band's earliest songs consisted of a more punk rock style, such as on their first single, "Drive by Negly." The band continued recording demos with the expectation of eventually recording their debut album, but ending up issuing a compilation of those demos as their first album Junk in 1997. A split single with Jimmy Eat World, including the song "Early Stars," was released in early 1998.
Later in 1998, the band released their second album, This Afternoon's Malady, which marked a notable departure from the band's more indie rock leanings.
In early 1999, the band added Mark Murino on second guitar in order to expand their live sound. Not long after, the band undertook a European tour with Kill Holiday.
Near the end of 1999, Jejune began experimenting with more pure-pop leanings and prepared to record their third album. However, tensions in the band regarding the new direction led to their breakup in early 2000. Later that year, Big Wheel Recreation released a compilation called RIP, which consisted of the completed demos for the third album, tracks from released singles, and a handful of unreleased songs.
