Karen Welling, founder of Welling Coaching, is performing at Somerville’s Porchfest from 2 to 4 p.m., May 21. Welling will sing with the indie rock/jazz band Steve Thomas & Real Incognito, and play piano and sing with Salsa and Brazilian jazz group Mambo Doble.

“Porchfest is a truly uplifting community festival, featuring many different kinds of music on people’s porches, in their driveways, and yards,” says Welling. “It’s a lot of fun with a lot of good feelings generated, and I’m so happy to be a part of it again.”

The event, which takes place from noon to 6 p.m., is sponsored by the Somerville Arts Council, and other acts range from Bollywood funk to Moroccan, Balkan and American space rock music on porches throughout Somerville. To see the schedule, visit SomervilleArtsCouncil.org.
