For improvisation, no-one will ever match Ornette Coleman. I mean, okay, he's not even a guitarist, but in terms of music in general, I'd rather listen to him than Liquid Tension Experiment or Dream Theatre any day. If we're talking in guitar-rock terms, I think Phish trump Liquid Tension Experiment for improvisational skill. Trey Anastasio is a much more engaging and entertaining improviser than John Petrucci.
