Pittsburghers are notoriously wary about sitting outside, listening to live music, eating good food and drinking drinks in the summertime. But against all odds, the weekly concert series Weather Permitting has persevered for six consecutive seasons of family-friendly outdoor shows at Shadyside Nursery. Season six kicks off with the Zimbabwean rock-fusion crew Mokoomba, Pittsburgh's premier reggae band Truth and Rites, and food from Brassero Grill, Gyro's Nat, and Pittsburgh Smokehouse. Bring the pups, bring the kids, buy a plant from the nursey. Heck of a Sunday.
