If you still havenâ??t heard about Tijuanaâ??s Nortec Collective, this is a good time to discover them. The collective of DJs, producers, and graphic artists mixes techno with Northern Mexican music (mainly banda and norteÃ±a) and has solidly established themselves as one of the coolest electronica hybrids in the world. NC members Bostich and Fussible are touring behind their Grammy-nominated Bulevar 2000, but Colombiaâ??s Bomba EstÃ©reo (pictured) could very well steal the show. An irresistible, groovy, hypnotic, and aggressive fusion of dub, hip-hop, electronica, and Colombian folk (mostly cumbia), Bomba Estereo is the type of band that hooks you in a second. Sexy singer Liliana Saumet is not the worldâ??s best rapper, but her attitude and charisma are hard to match, and there is a solid band behind her. Nortec and Bomba EstÃ©reo are two of the key members of the roster of Nacional Records, the leading Latin alternative label in the U.S. If youâ??re new to the genre, this show is a great introduction. Free, 6pm, Pearl Park Amphitheatre, 369 Pearl Pkwy, pearlechale.com.
