Los Angeles indie quintet Inner Wave play a bright, experimental mix of pysch-pop and synthwave that earned them a significant streaming presence and die-hard regional following in the mid-2010s, thanks in part to songs like “American Spirits” and “Eclipse.” The group’s quirky but catchy songs and combined Filipino, Colombian, and Mexican heritage have helped make them underground stars in the area’s Latinx indie rock community alongside acts like Chicano Batman and Cuco.
