Here are some prog & jazz fusion guys you may not know about.
This is Jef Lee Johnson. The playing is a bit 'out', but if you like jazz or Zappa or that kind of shit. you'll appreciate this.

Skipped the vocals on this one, cause he wasn't always the greatest singer, but you can check it out if you're so inclined:

Awesome instrumental version of "Knockin' on Heaven's Door" that starts slow & goes insane:

This is Mike Keneally, Frank Zappa's last 'Stunt Guitarist' in the mid/late 80's after Steve Via. No vocals here, cause once again, his singing is inconsistent:

This is a good song by Keneally, with some decent vocals & with Zappa-esque elements in some of the runs, but on acoustic:

This is a unique tune that's mostly instrumental called "Lightening Roy". It gets a bit weird & goofy when the vocals come in. Zappa guys will appreciate it, & I love this kind of thing.

Speaking of Zappa alumni, this is Adrian Belew, who was Zappa's 1st stunt guitarist. He also played with Bowie & The Talking Heads, among others, & was King Crimson's frontman in the 80's till the mid-2K's. This is an instrumental with his power trio called 'E'.
