Steve Earle and son Justin Townes visit 'Treme'

On top of being a spellbinding, all-too-real portrayal of post-Katrina New Orleans (produced by the same folks who brought us The Wire), it's quickly becoming one of the finest musical programs on television. In just a handful of episodes, we've gotten live, gorgeous full-length performances from Elvis CostelloDr. John and Allen Toussaint.
