Two current artists have taken Cumbia, one of the oldest and most popular rhythms in Latin America, and have given it a modern twist. Instead of playing traditional instruments like the accordion and maracas, they’ve turned to synthesizers. These sounds can be heard on the new album “Ruido Tovar.” It’s by Meridian Brothers and Mexican Institute of Sound. Camilo Lara is the brainchild behind M.I.S and speaks to host Marco Werman.
