eTown, the Colorado-based live music radio show, recently opened the doors to eTown Hall, its very own venue in downtown Boulder. The solar-powered concert room gives the nationally syndicated NPR program its own dynamic community space to stage and record music as well as host conversations with some of the world's best musicians. Check out a live taping with '90s big band-swing heroes Big Bad Voodoo Daddy and fiery songsmith Nellie McKay. Wed 7 p.m.
