If you don't own this, I'll tell you now- buy it! This is perhaps the ultimate jam album (I'm not kidding) and its at single album price! Recorded in an extinct Hawaiian volcano it is as mind-blowing as the concert site. One of my best friends' brother-in-laws was stationed at Pearl Harbor in '72 and was actually at this show- he still can't quite describe it- you get the idea.
I've seen Santana near 30 times live (including once with Buddy Miles in the mid-80s) but none of it touches what he does on this recording. The accompanying brass and flutes on this record take the sound to a whole other level and Carlos plays with a fury that is unmatched on his other stuff- which I own all of. Absolutely not to be missed!
Best,
