Like a junkie relentlessly searching for the next fix, a certain type of irredeemable music obsessive is constantly on the prowl for a new sound. The best highs are achieved by the discovery of a previously unheard genre. My pal SA is a reliable plug. I sensed I was in for a delirious score when he recommended Saturno 2000: La Rebajada de Los Sonideros 1962-1983. My feet haven’t touched the ground since I injected the novel grooves directly into my cranium. The new Analog Africa release compiles remixes of 14 cumbias that are slowed and stabilized to suit Mexican sensibilities. I experience the doctored music as a cheerful foreshadowing of Houston’s sinister chopped-and-screwed movement of the 1990s. Toying with YouTube’s playback speed settings on tracks including “La Borrachita” heightens the delirium.
