A diamond of turntable precision is tucked into a Glendale, California, brick-and-mortar DJ school, the Beat Junkie Institute of Sound, co-founded and co-operated by Los Angeles’s next-level-talented DJ Babu. The institute, teaching 12 students at a time with personal DJ booths, is led by an internationally known crew of teachers, The Beat Junkies, who have been lighting up the Southland since assembling from different backgrounds in the 1990s.
