Enjoyed only a few shows at iota, most recent I can remember was Ben Sollee. . . being on the MD side I didn't like making the drive
(and risk the odd parking situations) too often.
That being said, the best show any band I have been in has played was at iota; wonderful, clear well monitored sound and responsive staff.
That same band broke up two weeks later after playing possibly our worst show; a rainy day, outdoor, cancer benefit in the middle of the Damascus High School track (to roughly no one)... and someone's GF absconding with band funds and our drummer's cocaine.
Side note, invited my first girlfriend (pre-dating) to that same iota show only to absentmindedly blow it (not catching her signals, I was a late bloomer) and have her hook up with the door man at the time...
He got locked up with a DUI or something and in the intervening period of time she and I got together. Our relationship, much like that band, ended spectacularly.
