Since they qualify for the 15 studio release requirement, I'd list Roger Taylor of Queen.
Granted, he got lazy in the 80s with the programmed drums. In the 70s, he had to do most of the BVs on tour (as well as the occasional LV). His drumming on Queen II (specifically 'Father To Son) and the LPs 'A Night at the Opera', 'A Day at the Races', and 'News of the World' was just so spot on. As to 'Sheer Heart Attack', especially for 'Brighton Rock' and 'Stone Cold Crazy', as well as 'Killer Queen' and all other tracks, his solos and fills were aces.
No idea why he laid back so much on his solo releases, other than songs such as 'Let's Get Crazy', 'Man On Fire', and a few others.
