Sun209 is based in Nashville, so we’re taking Austin’s claim of being the “”Live Music Capital of the World” with a grain of salt. That said, the line-up at the Keep Austin Weird Festival was truly impressive, particularly the bands that hit the stage in the late afternoon and early evening. There’s some of the Band in Deadman and Motown/Stax in Suite 709, but both build on those Old School roots in fresh and vibrant ways. The new Suite 709 CD “Keys” is due shortly.
