Located below the larger Nile Theater venue, The Underground harks back to those underage days, when the best shows you saw were hosted in someone's basement. The Underground is quite literally a basement — you can see utility beams and pipes on the ceiling, and there are mounds of crumbling dirt and drywall in the corners of the room, where dampness and decay has taken its toll (you won't find such moldy charm above ground). But aside from its basement aesthetic, The Underground has some great acoustics (not counting the occasional sonic bleed-through of whatever show's going on upstairs in the Nile). There's enough space for about 75 people to fit comfortably, but because the venue's a basement, it can get really stuffy and hot when it's packed. The only downside for would-be concertgoers at The Underground is there's no elevator. So if someone's physically unable to climb up and down the stairs, the best they can get is to listen to the show from the lobby or from the top of the stairs.
