Favorite Instrumentals...

[CKJ]

Cacophony - Concerto is a fav of mine

Then mostly anything by Buckethead. ie. Soothsayer, Fizzy Lipton Drinks (beginning and end), Machete, and for some reason I get a kick out of Sketches of Spain (for Miles).

Agent Steel - The Day of Guyana, kicks ass

And have you guys heard anything by andy james? or micheal romeos solo albums? theyre both fckin imba in my humble opinion (im a nut for tapping though :P)

Ive always liked the Rush instrumental stuff. Even if there are a few words here and there I think they still count as instrumentals.
