I was actually going to start a cumbia thread today.
Okay, to start with, here's a newer 9-piece instrumental cumbia group from Mexico City, Mexico named "Sonido Gallo Negro" which translates to "Black Rooster Sound" in English. The name of the album is "Sendero Mistico" (Mystic Path) and features a psychedelic sound running throughout the album along with some chica, and surf music blended into the mix. This is their second of three albums they've released so far since 2011...
