Loyola Marymount University might not have the same enrollment as UCLA or USC, but the Jesuit institution in Westchester still makes a mighty roar with its campus radio station, KXLU. Ironically, despite the university’s religious focus, KXLU itself is wildly freeform, with its DJs playing a much wider variety of music than any other station on the local radio dial. This year, the station’s annual, free festival, which is held outdoors at Lawton Plaza, features a diverse cross-section of underground sounds, including Mndsgn, the Filipino-American hip-hop producer who weaves glitzy electronic textures within his Stones Throw releases. Other highlights range from the urgent, synth-pumped post-punk of Sextile to the seedy punk claustrophobia of Wild Wing. L.A. duo Band Aparte cloak their darkly romantic songs in goth shadows, while teen gals Pinky Pinky are a heavy, guitar-based, blues-prog power trio.
