He scrupulously avoids pitching himself in his SN&R column, Clubber, where he writes about other local musicians. But Christian Kiefer is also a singer-songwriter of some note, with a few good records to his credit, and he occasionally performs locally. If you’re curious, you can catch his act this Friday night at the True Love Coffeehouse, 2406 J Street, with Jeff Pitcher opening. The show starts around 9 p.m., and the cover’s $7. Get there early because, well, see Kiefer’s latest column for the reason why.
