Yet fun as hell!
Instead of watching stuff like Rock Discipline and playing shapes/modes/etc, I'm watching stuff like this:
╗ Learn How To Hold Drumsticks With Proper Grip
I'm trying to learn both drums and piano at the same time, and it's pretty interesting switching from something as interactive as drumming to something that requires a light touch/feel like piano.
Good stuff. If you're bored with your shredding or just want to do something cool in your spare time, try picking up a new instrument.
Learning piano is one of the most educationally valuable musical things I've done.
I look forward to studying rhythmic rudiments next year.
