Music for IVE

I need to teach some Oaxacan music to the International Vocal Ensemble. I want to do one or two songs from the coast, but I can't decide on which one is better.

I just watched the 2004 Guelaguetza DVD and saw the "Danza de los Diablos" from Santa Maria Huazolotitlán and I think it captures the humor and the uniqueness of the Oaxacan coast really well. The instrumentation they use is:

1. Flauta ó harmónica.
2. Charrasca ó "quijada de burro," que se rasca con una pata de venado
3. Arcusa/Arcuza/bote/tigra - "especie de tambor de origen africano a cuyo cuero se conecta una vara que, untada con cera de Campeche y tallada con la mano, produce un sonido como el de la respiración de un gran felino."

Another interesting music that is on that DVD comes from Juchitan, where they use the following ancient instruments:

1. Flauta de carrizo (ditch reed flute)
2. Carapachos de tortuga, batidos con astas de venado
