Phish

Soon after forming the band, Phish (aka The White Tape) was created from four-track recordings which the band and band members mixed, dubbed and circulated as a demo.
It consists of an assortment of four-track recordings from 1984-1985, including four songs recorded by all the existing members of Phish as a band: Alumni Blues, AC/DC Bag, Slave To The Traffic Light, and Dog Gone Dog (a/k/a Dog Log). The balance was recorded separately by the band members and blended together from 4-track cassettes to create the album as we know it. Trey has said The White Tape exemplifies, perhaps more than any other studio effort, the band's unbridled creative freedom of the day. 

The original art for the cassette demo was created by Trey himself and was updated for release by artist Jim Pollock.
