Sarah Lee Guthrie and Johnny Irion“Authentic.” “Timeless.” “Harmonious.” “Exhilarating.” Any or all of these adjectives could describe the folk-rock sound created by Sarah Lee Guthrie and Johnny Irion (eye-ree-un).

Johnny Irion recently followed up with 2007's Ex Tempore,which, as the name implies, is a spontaneous sounding recording, but with a depth that recalls the cosmic American music from the heyday of Gram Parsons and contemporaries.

In perfect harmony with the evening, Jayhawks drummer, and now well-established singer-songwriter in his own right, Tim O'Reagan will open.
