For anyone who says live music has not changed for the worse, I present No auto-tune, no synths, just great musicians playing their hearts out. If there is a "real" recording of this out, I would love to purchase it. I think Terry Kath is the most under-rated guitarist in rock, and Peter Cetera was certainly no slouch.
But none of that sounds like the cd! Compare Tanglewood with any of their recent live stuff...and if I point that out, I usually get clobbered by "things are the same today as yesterday, you just have a foggy memory" crowd.
