Yeah, I'm not into metal, but it just goes to show that real musicians respect good musicianship regardless of genre. Even Jaco talks about being in a Country and Western band for a year...saying he had a blast.
I'm glad this was made. It certainly cleared up a few things for me. It's sad to see a genius musician fall so far, and never have the chance to rebound from it. Jaco...more than just a great bass player.
(I have a few of those Joni Mitchell albums on original vinyl. Shadows and Light is one of my favorites, and the first time I was exposed to Jaco and Metheny.)
