At the intersection between two vibrant Los Angeles music communities, the well-entrenched East Side indie rock scene and the burgeoning Latino hipster scene, exists Wait. Think. Fast. A unique hybrid of these two distinct worlds, the band marries sultry pop songs with bilingual vocals, melding two tongues into a singular sound that has been exciting listeners in both English and Spanish since forming in 2007. Having earned critical acclaim and an increasing legion of hometown fans with its 2009 EP, “Vuelve al Mar” (Origami Records), the band decided to take itself out of its comfort zone for its first full-length, Luces del Sur, scheduled for release on September 2.
