As a jazz fan, a rock fan and even a FZ fan, I am shocked that it took me so long to finally listen to this album.  This is one that really lives up to the hype - to all the accolades fans have been expressing for years.  For freedom of expression, the title cut reminds me a bit of Bitches Brew, but more accessible, to my ear.  It has to be the fastest 13 minutes on record - ie, it ends all too soon.  Other tunes do remind me of So What, with the smooth flow.  Acquire it now - don't wait forty years, as did I.
