Query: Well worth the money!

El Gran Silencio's songs are a playful, incisive, and well played mix of rap, cumbia, norteño, tex-mex, rock, polka, funk, vallenato, and ska. I defy you to listen to Perdido without jumping up and dancing... and their slower songs like Criaturas de Luz are beautiful. A great combination of gifted musicians and intelligent lyrics.
