How about an evening of acoustic retro rock, some soulful serenades, a cowboy crooner, and maybe a poignant poem or two?  It’s DOC MEHL (guitar and cello) and ERIC CHRISTIANSEN (keyboard and harmonica) playing at their favorite coffee shop, Zoe’s Coffee! Zoe’s is located at 11225 Decatur St. #200, Westminster CO, (303) 246-6173. www.zoes-coffee.net. It's not heavy metal… it's heavy wood!
