UK radio DJ John Peel was responsible for inviting a succession of then-unknown, highly-extreme hardcore/punk/metal bands to lay down tracks to air on his national UK radio show in the late '80s. Causing intense debate at the time as members of the public were aurally assaulted by the most extreme music they had ever heard, John Peel continued his hands-on support to the fledgling scene for the next four years.
Carcass recorded two separate sessions in 1988 and 1990, with John Peel purportedly saying following the first, "Is it too soon to nominate this as the session of the year?"
