 He is primarily known for his powerful tribal drumming style, which includes the use of the tom toms as a rhythmic component that replaces the traditional hihat and ride cymbal.
 He credits the jazz drummers Art Blakey, Max Roach, and Elvin Jones for inspiring this approach to his drumming style, as well as the rock drummers John Bonham, Keith Moon, and Neil Peart.
 He has also stated that the heavyweight boxer Muhammad Ali inspired his drumming at a young age, saying, "Ali was so incredibly fast on his feet, and his hands were both light and heavy at the same time.
 Float like a butterfly, sting like bee, that's the way a great drummer should play – light and heavy, the way Ali boxed."
