John “Drumbo” French (Captain Beefheart’s Magic Band)
Captain Beefheart let Drumbo help compose the chaotic avant-masterpiece "Trout Mask Replica" (some people consider it that, it’s more about who took inspiration from the album though), as Beefheart had a very narrow view of music theory. Drumbo played his heart out on that album, developing some of the whackiest and hard-to-understand lines ever made.
Phil Collins
Bet yall saw this one coming, it is only fair to include who many people consider the “actual best drummer of all time,” Phil Freaking Collins. A multi-instrumentalist, social icon, unstoppable artist, creator of the Tarzan soundtrack, half of Genesis, and genuinely an outstandingly creative percussionist. There's not much else we can say here outside of singing the praise of this genius. All hail Phil Collins.
