Three performances that most shaped where my musical tastes would wander are all from one concert film and album -- the first rock superstar benefit concert of its kind -- The Concert for Bangladesh (1972). Those performances were from Bob Dylan, Leon Russell and Billy Preston. Here's a little taste, Preston's song for the two Madison Square Garden shows in the summer of 1971.
Preston, the keyboard power behind the Beatles (at the very end) and the early seventies Stones, shows his gospel roots on this one, with all the hip rockers thinking they are in heaven. For me, when the movie finally did hit town, I was in heaven too.
