Context: Blind Melon (Stylized as BLind MeLoN) is an American rock band formed in Los Angeles, California by two musicians from Mississippi and one from Indiana.  Best known for their 1993 single "No Rain", the group enjoyed critical and commercial success in the early 1990s with their neo-psychedelic take on alternative rock. Letters from a Porcupine is a 1996 documentary style film made up of footage from the musical career of the alternative rock band Blind Melon including music videos, interviews, live performances and home movie footage. Porcupine Tree were an English rock band formed by musician Steven Wilson in 1987.  The band began essentially as a solo project for Wilson, who created all of the band's music.  However, by 1993, Wilson desired to work in a band environment, and so brought on frequent collaborators Richard Barbieri on keyboards, Colin Edwin on bass and Chris Maitland on drums as permanent band members.  With Wilson still in charge of guitar and lead vocals, this would remain the lineup until 2001, when the band recruited Gavin Harrison to replace Maitland on drums. The Cult are a British rock band formed in 1983.

They gained a dedicated following in the UK in the mid-1980s as a post-punk/gothic rock band, with singles such as "She Sells Sanctuary", before breaking mainstream in the United States in the late 1980s as a hard rock band with singles such as "Love Removal Machine" and "Fire Woman".  According to music critic Stephen Thomas Erlewine, the band fuse a "heavy metal revivalist" sound with the "pseudo-mysticism ... of The Doors [and] the guitar-orchestrations of Led Zeppelin ... while adding touches of post-punk goth rock".  Since the initial formation of Southern Death Cult in Bradford in 1981, the band have had various line-ups; the longest-serving members are Astbury and guitarist Billy Duffy, the band's two songwriters.
