DCist hosted "Unbuckled" tonight at DC9. We caught the opening act, Motel, and captured a bit of the guys freestyling.
Just a few years ago I knew of DC9 (9th just south of U St. NW) for certain dance nights, but rarely thought of it as decent venue for shows. Either I've changed, or they've changed, because now I pay attention to their schedule - and they regularly pull in solid local and regional groups and charge a reasonable $8-$12 a show.
You can visit Motel online here, and check them out below (though, the sound is pretty garbled):
