Drummers, don't let this word, Rudiments: scare you into thinking this is about boring  'routines' ,,, or not for the 'cool kids'. 

Every great drummer uses Rudiments, whether or not they are telling you they do or not... put it this way; 

Not learning, or have control of the drumming "Rudiments" would be like trying to play baseball without being able to 

catch a ball or a football player not learning how to tackle...

 The Rudimental basics: give us what we need to attempt to add strength, and consistency, to a  "Beat" - and also 

playing it quickly, and controlled, and creatively.
