Cutting edge artists Steve Earle and Allison Moorer will be the guest of Air America‘s Katherine Lanpher this Sunday (4/24) at 8:30 p.m. at Housing Works Used Book Cafe in New York City. The event is free, but the organizers are asking attendees to bring books for donation. Katherine Lanpher is co-host of The Al Franken Show – her current project is Liberal Arts (which is still in pilot stage), an arts and cultural program for the left-leaning Air America. The Earle/Moorer interview/performance is Lanpher’s first live taping of the show. Steve Earle won the Grammy this year for Best Contemporary Folk Album for The Revolution Starts Now but, although the Country-fied Moorer is scheduled to sing, Earle will discuss his work as playwright and fiction writer. For information, call (212) 334-3324.
