52. Broken Arrow (Buffalo Springfield Again, 1967)
Until 1967, pop and rock musicians did NOT make records like this. Every bit as experimental as what the Beatles were doing with Sgt Pepper, this multi-part epic covers everything from LSD use to massacres of Indians and is equally diverse musically. It announced Neil as a major talent to be reckoned with, even by the high standards that Springfield had already set. And unlike many experiments of the time, this one still holds up today.
I have no idea why he used this title again for a 1996 album (the song does not appear there).
