21. Paul Gilbert
Guitar aficionados and critics know just how good Gilbert is on the instrument. A prodigy of sorts, Gilbert first earned acclaim with ‘80s’ metal band Racer X. Towards the end of the decade, Gilbert, known for his brilliant technique and speed on the guitar, joined forces with famed bassist Billy Sheehan to form Mr. Big. That band would go on to enjoy some decent commercial success in the early 1990s. Gilbert was named among Guitar World’s “50 Fastest Guitarists of All Time.”
