I'm at the pearly gates and they tell me I can only bring in one jazz cd

Miles Davis - Seven Steps To Heaven.

But why in God's name would anyone listen to jazz on CD? That ain't heaven.

Between a rock and a hard place! In heaven only one piece of music, sounds like hell to me. In hell, all your records warp! I think I would be shooting for limbo. I hear their power grid is pretty clean.

hands down fave- red norvo, "the forward look."

Actually, it's a trick question.
(Heaven is 52nd St., NYC, circa 1945).
Only those choosing Charlie Parker discs are allowed inside. 

one disc? Miles Round Midnight.  one song? Grant Green Idle Moments.
