If you get an opportunity, go see the Australian Pink Floyd act. They played at David Gilmour's 50th birthday party in 1995 and he said they were technically better musicians than any of the original Floyd. I think he was being humble. I never got to see the original, but did see the Aussies and they are phenominal. To experience a bit of Floyd's early genius, give this a view. Careful with that Ax, Eugene from Ummagumma.
