Once every summer, there’s a line around the block to get into SAM Remix at the Olympic Sculpture Park, and with good reason: When else does Seattle party around art until midnight outdoors? This time around, special events include Brazilian dance and music (to provide a soundtrack for Sandra Cinto’s giant, swirling water mural in the pavilion), an outdoor screening of Jaws overlooking the water, sunset sketching with Seattle artist Julie Alpert, the band BOAT, beats by DJ Riz, the making of wildflower seed bombs, and “Highly Opinionated Tours” of the park itself. (Olympic Sculpture Park, 2901 Western Ave, www.seattleartmuseum.org, 8 pm, $25)
