Yeah great choice MrDrums. JoJo is the absolute dope shyte when it comes to D n B grooves. Zach Danzinger is pretty dope as well. Theres a group called KUDU out of New York who has a great drummer not sure what his name is but he slams some hardcore Drum N Bass. Also when you go to JoJo Mayers site watch the NERVE Movie it's too cool.
I was blown away when I saw that movie!! It's curious because I've always fancied triying to incorporate breakbeats into my playing, but most of the stuff jojo plays I didn't even know it was humanly possible to play (at least not with such machine-like precision!)
