Congrats, Bitches Brew, you made it to 40 without fading into irrelevancy.
You are still bad ass in your flights into the unknown and in your pioneering forays into tape-editing. Any good jazz record born after you just wants to sound half as cool, and so do plenty of noise-ists, avant-anythings, and psychedelics of every shade and color.
You are so groovy that we swoon to this day. That is all.
