these bands are the result of effective drug use. thats one hell of a list. I had no idea YES was around in the 60s. I thought for sure when I heard Roundabout which steve posted was new in the 80s. I apparently have some lapses in my music history. Usually from those bands from across the pond. Even the who's and pink floyds music is somewhat odd to me. But of course i was never a drug user. I do wanna start however. Maybe some psychedelics and a laser light show to start. Or would that freak me out too much?
