Crass
Crass released their first record in 1978. It was called The Feeding of the 5000. It was meant to have 18 songs on it, but one song was banned by the people who worked at the factory where the records were made. This was because they thought it was blasphemous. This song was  called "Asylum". The band instead released the record with a 2-minute gap where that song had been, which they called "The Sound of Free Speech". After this they set up their own record label, Crass Records. This was so that they could control what was on their own records in the future. They re-recorded and released the song that had been banned as a single. They also re-released the first LP with the banned song put back on it.
