MUSIC—Throw some canned goods in a sack (they’re good for admission or post-legal-weed hunger pangs) and slowly roast yourself red while listening to the blues. The Waterfront Blues Festival is back, and this year’s lineup features Allen Toussaint, Buddy Guy, Macy Gray, some Allmans, and dozens more. DIRK VANDERHART
Tom McCall Waterfront Park, SW Naito & Columbia, Thurs-Sun, shows start at noon, suggested donation $10 (canned goods work, too), all ages
DANCE PARTY—Ecotrust’s annual Sundown concert series is a beloved summer tradition, featuring free live music and low-pressure awareness boosting about environmental concerns. Portland Cello Project kicks it off on a buoyant note with an all-ages dance party under the theme of “climate.” MARJORIE SKINNER
