Most people haven't heard of Coroner, a truly great progressive thrash band. It's sad, because their melodies, lyrics, technicality and progressions were mature and continued to stabilize and grow throughout all their albums. Ron plays immensly busy and melodic lines throughout the bands work and also provides raspy vocals. A lot of the time, he doubles the guitar line (which is logical and reasonable, as they are a trio), but his fills can get quite fun and interesting. Take, for instance, his line on what I believe is the second solo in "Masked Jackal" off of Punishment for Decadence- very bluesy and jazzy. And his incredibly speedy two-digit fingerstyle matches guitarist Tom Vetterli's (who's now in Kreator) shredding sweeps, taps, and molten riffage. Anybody into older prog like Rush and/or metal should check these guys out- they're worth your time.
