Marc:
I'm a music lover & a Assistant for a local band where I live. Music is alive & well around these parts & I'd always rather encourage music as opposed to fighting. Maybe I sound like a passivist, and perhaps I am in part, but the bottom line is this: Music will be something you can share with others for the rest of your life; it is something you can give to your children & generations old & new alike. MMA could get you seriously hurt, which would hamper the rest of your life considerably. I don't think I've heard of many serious musucian injuries, unless, of course, crowd-surfing or lighting instruments on fire is your schtick! Good luck in whatever you choose!
