While “family-friendly” and “techno” may seem like water and oil, allow your mind to be blown by just how well the two can combine. L.A.-based arts and culture promoter Green Galactic will be celebrating its 20th year in the biz with a free, family-friendly techno concert at California Plaza. The Green Galactic 20th-Anniversary Celebration, a collaboration with Grand Performances, includes three hours of performances by techno gurus Plaid, Pole and John Tejada. If you're in Los Angeles for your five minutes of fame, take note: Tejada plans to use footage from this concert for a music video for his new track, “Anaphora.” This isn't rave music — the soothing sounds of the three electronic musicians are palatable even if you're not into glowsticks and butterfly wings. So pack a picnic basket and round up Gram, Gramps, little Timmy and the whole gang to delight in some techno tunes. Alcohol is permitted, so don't forget to bring a bottle and a corkscrew. California Plaza, 350 S. Grand Ave., dwntwn.; Sun., June 30, 7-10 p.m.; free. facebook.com/events/185705058248108.
