It may have been the 60's, but I don't have the resource to verify it. I believe the same thing happened to Ornette Coleman. From what I remember reading from somewhere, he was "paid" or "told" to sit out a couple of years (somewhere between '63 and '66; The Empty Foxhole was his first studio album in years) by thugs who may have been hired by the major labels because artists like Coleman and Taylor were taking a chunk of the business away from the commerical acts. Again, no way I can verify the story, just remember reading it and I could have it wrong. Does anyone know if that actually happened or not? I think Sunny Murray was also targeted, which he talked about in an interview he gave awhile back. I think the other stories came from an article I read about the BYG/Actuel label and their dealings, but I'm not sure.
