I was watching this here video of Three Trapped Tigers playing live (http://www.youtube.com/watch?v=IH5H07p_NjE) largely to see their drummer going apeshit. I saw them supporting Deftones at the start of the year without knowing anything about them and I was blown away. By the band in general, but specifically how incredible he was. Few things better to see live than a loud as fuck but technical drummer. I also remember the drummer from HEALTH (http://www.youtube.com/watch?v=ps0Q0fzbjrs) being the loudest I've ever heard (this video doesn't really do it justice). I have no idea how he didn't bust right through the skin of his bass drum.
General thread to post videos of really good drummers, then.
