A Good Day. It'92s bound to be a good night on Monday, Nov. 17, when the L.A.-based singer-songwriter comes to WorkPlay, opening for Blue Note label-mate Amos Lee. Ahn was born in Georgia, grew up in Pennsylvania and headed for the West Coast as soon as she finished high school, opting to pursue a career in music rather than a college degree. She plays acoustic guitar and harmonica (and, when she'92s not on stage, cross-stitches!) and sings sweet and low but not saccharine. Lee '96 well, let'92s just say that Lee has opened for Bob Dylan and Paul Simon. "Reg'92s Coffeehouse" is presenting the show, which is all-ages and costs $26.50. Call (205) 879-4773 or go to www.workplay.com for tickets.
