Some folks love singer/songwriters. Other folks groan and picture a melancholy fellow perched behind an acoustic guitar prefacing songs with, "And this one comes straight from the heart." STEPHEN LYNCH is a singer/songwriter, but NOV. 5, he'll prove he's not sensitive at all. Inspired to go into music by This Is Spinal Tap, Lynch writes heartfelt confessions to his lovers about his herpes and other darkly comedic fare. So if you've been looking for a ditty to sing to your fugly baby, this is the musician for you. $25. 8 p.m. Variety Playhouse, 1099 Euclid Ave. 404-524-7354. www.variety-playhouse.com.
