pink floyd concert fillmore west gave me flashbacks, seen them  twice at (syria mosque) in pittsburgh before they got big & started doing arenas (civic arena & 3 rivers stadium). highlight for the mosque was "careful with axe eugene" when roger screams & flashpots go off filling it with smoke, then gilmour goes into a soaring guitar that  takes you out then slowly brings you back, outstanding, basic amps & nothing more, but they did have speakers in the back for the songs from the "atom heart mother" opening they played entirely (anyone from mckees rocks out there)
