@Kaleidoscope Totally agree about Yoshiki as well.. He still pretty damn amazing for needing to play with a neck brace and having all that wrist pain..
Others I'd add to the list are Sujk (DELUHI), though I see he's already been mentioned a couple times.
Kawauchi Tooru (12012) is another pretty good one and he's improving with every release.
Nero (Merry) is also a favorite.
And one of my top ones is Kenzo (soon to be ex. ayabie). I find his drumming to be pretty f---ing amazing. Always the highlight for me when I listen to ayabie songs, though with their latest few releases, not as much. He's also got an amazing set up for his drums.
