Influential DJ, producer, and label head Jace Clayton digs deep into the world of digital cumbia bootlegs to find gold.

Since his mixtape heard ’round the world, Gold Teeth Thief, dropped in 2001, Clayton (a.k.a. DJ /rupture) has become well-known for telling us what we should be listening to. For the past couple years, he’s been knee-deep in cumbia and Latin beats. Here, he teaches us about cumbia and takes us to bootleg CD shops in San Francisco’s Mission District to sort the wheat from the chaff—hardly an easy feat in the world of digital piracy.
