Guitarist Al Petteway runs a musician’s marathon at almost every Wammie Awards show. He races to the podium each time his name is announced, delivers a speech, and dashes offstage carrying yet another token of his peers’ reverence. “We just say he’s a “multiple Wammie winner’ at this point,” laughs Becky Flanagan, Petteway’s booking agent. “We don’t want it to sound like we’re keeping score.” Though most of these accolades have come as a result of Petteway’s collaborations with local folk artists, don’t be surprised if his latest solo release, a collection of acoustic instrumentals titled Midsummer Moon, garners more statuettes. Particularly enlightened are his live-in-the-studio take on the traditional Scottish ditty, “Wild Mountain Thyme,” and “Amy’s Tears,” a moody original probably meant for labelmate Amy White. Petteway’s next local shows take place Oct. 1, when he plays both the Takoma Park Street Festival (with White) and the Herndon Folk Festival (as a backup for Tom Paxton). To order Midsummer Moon, send $15 (includes postage) to Maggie’s Music, P.O. Box 144, Annapolis, MD 21403.
