Here’s one of my favorites:  Frank Zappa soloing over his twisted cover of an Allman Brothers tune in 11/8 time;  –Whipping Post!

And “Watermelon in Easter Hay”

This clip contains my favorite rock Marimba solo (and a bad edit, too) :  Inca Roads.

Why all the guitar posts?  I'm inspired after discovering today that my Gibson Classical guitar has a history!   (thanks, Vintage-Guitars!)
