“This one changed my life more than any other record. Nobody had ever heard music like this before. Here were a bunch of jazz musicians coming together and fusing the intricacies of jazz harmonies with the power and drive of rock. Some people just do it for you, and there were things in the melodies and the harmonies and the riffs of this music that brought me to another place.

“In the middle of everything, sitting in the driver’s seat and propelling the music, was Billy Cobham. I don’t know if I can pick a single song here, because every cut is a fascinating study in time signatures. I wore out the grooves on every part of this record trying to figure out what Billy was doing.

“Meeting Of The Spirits is in 6/8, but there’s always an anticipated cymbal crash that surprises you. Dawn is a beautiful ballad, but it in middle it goes into something that’s in 7/4 or 7/8, whatever you want to call it. The Noonward Race is a really fast, intense song with tons of ghost strokes. And on Vital Transformation, Billy plays one of his signature grooves.

“Dance Of Maya is probably the coolest song on the record. It starts out with a guitar line that sounds like quarter notes, but when the band comes in, they’re playing a shuffle in a completely different time feel from those notes. As it turns out, the time signature is 20/8. Unreal.”
