Start off with the fact that Mike Stern has diversified greatly on the last two releases, this is NOT pop but in fact some great rock/jazz fusion with more talented personnel than the law should allow. I have only listened to pieces so far, however the addiions of Steve Vai and Eric Johnson, also Martin, Medeski & Wood, and throw in some other stellar musicians and you have quite the makings for some interesting combinations in the studio. I bought "Who Let the Cats Out" and it is amazing. This may prove to be even better. Without even hearing all of it, I can recommend this CD to any who are jazz/rock, or jazz/blues guitar enthusiasts. The bottom line is Mike is making some fantastic music with some incredible musicians, and Heads UP Int deserves a lot of credit for not trying to put him in a box.
