Bloodshot Records, the indie label that put "insurgent country" on the map, will be hosting a showcase at the Metro in Chicago on Saturday night.| The bill will include the liquor-soaked honkey tonk stylings of the Waco Brothers, as well as performances by Rico Bell, Moonshine Willy and Sally Timms. JAMtv will webcast the festivities starting at 10:00 p.m. EDT (www.jamtv.com/venue). The show is a must see and according to head Waco John Langford, "You can expect lots of dazzling cowboy shirts."
