For those decades I was out playing in variety bands, and didn't listen to UK radio. I consider myself to be a (modest...) musician, and could name no bands from that era, either. On the other hand, I could reel off a list of certainly 50, maybe more, classical composers, most of whom I listen to and appreciate often. Not everyone attends clubs, discos, raves, parties and such. My own listening, at the time, was either my own, and my groups', compositions, or West Coast acid stuff, Brazilian sambas, 'typique' music from the West Indies and African tribal stuff. I cannot name one single Japanese band, either. The World is a very wide range of stuff, and UK 'indie' is only a speck of what's out there.
