Brann Dailor is the drummer for Mastodon, an American heavy metal band based in Atlanta, Georgia. His style is very jazzy and prog-rock influenced and has been considered by many to be one of the best and most exciting modern drummers. Many describe his style as "organized chaos". His style is polyrhythmic and very fill-heavy, rarely using conventional drumming methods and common rock beats. He has stated in interviews that his favorite albums are Stevie Wonder's Songs in the Key of Life and Genesis' The Lamb Lies Down on Broadway.
Many predict that he will emerge as a premier rock drummer in the next few years, as Mastodon achieves greater mainstream success, and Dave Grohl (ex-Nirvana drummer, Foo Fighters frontman) recently claimed he thought Dailor was the best drummer in the world.
