What a coincidence, yesterday for the first time I *really* listened to the Mahavishnu Orchestra vinyl standing in my shelf for over 4 years now. It's very complex stuff, so naturally I still have to get into it, but I like it. JMcL is a crazy good guitarist, and his band is insane. Still, I prefer other Jazz-influenced prog, especially UK. Their debut album is spinning right now and it never fails to blow me away.
