Yeah, back for the attack sounded terrible to me, but his solo stuff, lynch mob, and even the two dokken reunited albums were awesome. And the Lynch/Pilson project is tops all around.
If you haven't heard of Criss Oliva, look again.
Me, I like guitar. I like loud squeals and pinch harmonics that only dogs can hear, tapping that would redefine what Fred Astaire popularized, sweeping that would make a janitor jealous, and most importantly great melodic HOOKS (like the greatest hook writers of all time Björn Ulvaeus and Benny Andersson). Singing is not a requirement.
