alankin - The music on Live at the New School Volume Two was recorded in 1974, one year after the first Live at the New School LP, which was recorded in 1973. They're entirely different concerts.
Until recently, I'd also assumed that the music on Vol. 2 was from the same concert as Vol. 1. But that isn't the case.
