If you feel a rumbling in the air this week, don’t look to the weather report. Instead, check out the schedule for the Asheville Percussion Festival . To the ears of founder River Guerguerian , this festival is as much about community as it is about music. “I look at it like there’s a kitchen, there’s 10-12 cooks, each cook brings one recipe,” he said. “You put the recipe on the table and we all work on it together.”
