Well I'm glad this thread is here!
I second the motion to have Mike Johnston listed as one of the featured drummers on this site. So here's my contribution.
I recently interviewed Mike for TheParadiddler.com. It was a blast! He is so insightful, focused, and is genuinely interested in the betterment of the student. Plus, as has been duly noted, he is a phenomenal drummer. World-class, in my opinion.
Interview - Mike Johnston
I think many drum students are fortunate that Mike has chosen to share his skills instead of play in a band. His enthusiasm is infectious, and he's inspirational to boot. Have a listen to the interview (it's a podcast), and let us know what you think!
