The other reviewer is telling the truth. It's a freaky, circa 69 blowout inlcuding a lot of American expats from the avant jazz circles floating around Paris in those days. The thing is, just to make a point, if you happen to love Coltrane's Ascension, well then, ... I just got my copy of Luna Surface and played it on a little box at low volume ... getting a satisfying ambient mix ... and I found this CD to be absolute pure joy. I started to smirk after about five seconds. It's the most transcendent soothing freaked out sound I've ever heard, well maybe except for Ascension. So if you don't know what I mean, maybe avoid this, but if you know what I mean, "forget about it" as they say around here.
