Waterfront Wednesday is back, so drop in with your blanket or lawn chair and catch alt-blues act Houndmouth with special guests, psych/hip-hop The Jesse Lees and alt-country crooner Sam Filatreau. Returning to its outdoor home, WFPK has drafted a stellar summer lineup. This year shows will be held twice monthly on the Big Four Lawn next to the walking bridge. The show kicks off at 6 p.m. and Houndmouth will hit the stage around 9 p.m.. There will be food and beverages available. One note: Leave the furry friends at home. This is a humans-only event.
