When I was 18 I saw Buffy Sainte-Marie sing "Now that the Buffalo's Gone" at the Gaslight or one of the other spots in the Village. The experience was very disconcerting. Buffy seemed to aim the whole song not so much at me but through me - challenging some core beliefs I had been raised on regarding goodness, tolerance, patronization, racial attitudes, etc. I bought the record the next day. It was a great album, but that one song always resulted in that same very conflicted reaction - putting me well outside my comfort zone.
