Residents Amylulita and Marcelo C. Baez, along with guest DJs and bands, take control of Fontana’s downstairs party room for this shindig devoted to alt-Latin music, covering everything from indie rock and electro to cumbia and baile funk. Tonight, the duo plays host to Denise Murz, the Argentine electropop princess who's making her U.S. debut with a live performance, celebrating her about-to-drop new LP, Gran Conquista.
