An excellent online resource if you are interested in the music of Colombia is "A Short Trip Through Colombian Music" by Andrés Muñoz Jaramillo, a graduate student in physics at the University of Montana. There's an amazing variety of musics, some very Afro-Caribbean in style, others more like the Spanish-indigenous mixes found farther south in Peru and Bolivia.
YouTube has a wealth of videos. Here is a (very fast!) performance of the pasillo "Vino tinto" ("Red wine"). It seems to be in 3 at first, but the more you listen to it, the more a secondary meter in 4 becomes apparent. (In other words, it could be notated in measures of 12/8, variously subdivided as 3x4 or 4x3.)
