Musicians (or performers of all kinds) take note of a nearby resource – One World Studios. It’s rehearsal space located on an alley off 9th St. NW, one block from the Convention Center. Two rooms, each with PA, mikes, guitar and bass amps and basic drum kits, all in good shape. Plenty of soundproofing as well.
I sat in there on Satuday with Swagfunk, a group that includes one of our neighbors, master drummer Al Warren, and found One World a great place to play.
One World advertises recording and engineering services as well. For more details: http://www.1worldstudios.com.
