KCRW DJ Raul Campos furthers the station’s pledge of eclecticism with his first mixtape, an overview of the style found on his nightly “Nocturna” show. At 90 minutes, Loteria offers a great feel for Campos’ extended set, starting off with Tijuana techno heads Nortec Collective before a meaty middle of Latin hip-hop from Cuarto Poder, Papashanty, and Choc Quib Town. Then Campos flips the (light)switch with a series of leisurely, luxurious electronic slow jams like Thievery Corporation’s “Exilio.” Here the proceedings get muy durmiente, but a Masters at Work remix of Sergio Mendes’ famous “Mas Que Nada” is one of many on Loteria’s latter half that make taking the gamble worth it.
