2 part question:
How many drummers out there sing? I do but I'm not so hot with harmonies.
Also how many famous singing drummers can you name?
I don't... yet, maybe in the future. I would also like to add Taylor Hawkins - Foo Fighters to that list
Improvising lyrics while playing?.......you're good.
The first time I played and sang, we were doing pre-production for my first solo c.d. By the end of an hour of getting the hang of singing into a mic while doing what needed to be done on the drums, I was soaked with sweat and felt like I'd run a marathon. After a few days though it started coming naturally.
Damn Michael good list. Do you sing harmony? Do you get a monitor?
