Edgar "Meshlee" Modesto of Buyepongo is the group's vocalist and also a percussionist who plays conga and guacharaca, a thin percussive instrument that's used in cumbia. The group's line-up is fluid, but at the center of it are Modesto and his brother Randy, who plays bass, as well as Jorge "Yuka" Valleo, who plays accordion, clarinet and guitar in addition to singing, and Angel Hernandez, who plays saxophone, clarinet and flute. 

The musical backgrounds of the members of Buyepongo run the gamut from punk to hip-hop to jazz to metal. The band itself began life as a cumbia outfit. After the second version of Buyepongo formed, they brought more nuggets from their collective knowledge of music into the mix.
