LERA LYNN Lera Lynn has long been the quiet darling of the Athens, Ga., folk/country scene, but that's about to change. Among other accolades, NPR's Gerrison Keillor was so impressed when he picked her ringing, lyrical soprano out of a pile of audition tapes that he invited her to share the stage with bluegrass great Sam Bush at the Atlanta installment of A Prairie Home Companion. Comparisons to a young Emmylou are somewhat of a given, but Lynn puts her own sultry spin on the country siren genre. Catch her while you still can at an intimate venue (with The Trishas). It's clear that Athens won't be able to keep Lynn much of a secret any longer. $12. Evening Muse.
