Been down this road before.A lot of the artists made no money at all at the time,because of lack of sales,or dodgy management.Or both.Covering records is about preserving anonimity for as long as possible,a dj's cutting edge if you like.
By playing out,and owning these c/u's,tell me how that affects an artist 40 years on.? In many cases,the artists recordings would ahve been buried long ago,never to see light of day again.Its a bit of NS fun for us, and many artists have benefited from the digging and tracking down done by lots a guys out there,when their careers stalled all those year ago.
