Street’s the stage

From weeds to weed, history to hip-hop, and art to science, you have choices for next weekend.

Palm Desert

Hit the street — or the rooftop of a massive parking garage — at the third annual Street, a music, art, fashion and food-truck festival with two stages where live bands and DJs play reggae, hip-hop and ska. Watch acrobatic skateboarding and mural painting, play basketball on a full-size court and tag a wall (legally). When: Friday Cost, info: Free. Familyfriendly. Dogs on leash OK. (760) 346-2121, lat.ms/palmdesertstreet

Cypress Park, L.A.

Here’s a chance to learn about the L.A. River’s native plants and animals while helping restore the habitat. You’ll pull invasive weeds, and get some exercise too. The California State Parks Foundation provides tools, training and lunch. Later, stroll on a nature-walk loop trail or bike along flat, easy paths along the river. When: Saturday Cost, info: Free, but registration is required. Ages 8 and older. No dogs. (415) 262-4400, lat.ms/riverrestoration

Chinatown, L.A.

Dopium spotlights artists, designers, makers and entrepreneurs in L.A.’s evolving Chinatown neighborhood. Sculptures, photographs, paintings, videos, light shows, music and food should arouse sight, sound and taste sensations — “like dopamine through the brain and opium through the vein,” its website says.
