Well, now that the mystery is solved, or at least my own adle curiosity is satisfied, I'll just have a little fun with the thread...
https://en.m.wikipedia.org/wiki/T._Michael_ColemanLike I was saying on the other thread, Coleman is one of the few bass guitar players to ever have successfully 'sold' the instrument to a larger bluegrass audience that usually doesn't accept anything other than an upright. (trust me - I've lived on both sides) His work with Washington D.C.-based headliners The Seldom Scene, (and later, crossover band Chesapeake) put him on a national stage with it. It still isn't commonplace, but I know I get a lot less of the stink-eye when I show up with a bass guitar... I can't help but think that was aided by this guy, and a few other brave souls.

He was also a sound-guy for a while, made evident in the lyrics to this little bit he did with the Scene:
"Some nights it feels right, the bass sounds nice and round,
There's always some fool in the back that stands up and yells-
TURN THE BASS DOWN!
Well sit down you old fool, it's not to much bass that you hear,
It's just the acoustics of the room, or that half-smoked joint behind your girlfriend's ear..."
Yeah man... that's my kind of bass player.
