Formed in early 2001, the band has been a consistent part of various music scenes ever since, marked notably by multiple tours of Mexico, Europe and the Balkans.

The duo was joined by Mike Raytis (percussion), Alberto Cuéllar (trumpet), and Mark T. Harris (drums) and subsequently started playing shows around the San Francisco Bay Area.

In July 2005, they released the 8-song EP Entre Cerveza, Ritmo, y Emoción..., again produced by Billy Gould but this time engineered by Jamie McMann.

The album contains show favorites "Mi Tierra", "Pinches Fronteras", "Plebe Por Vida", as well as the band's version of the Louis Jordan song "Run Joe".

Their high energy music is based in early punk rock and hardcore, mostly played fast, with melodic overlays from the trumpet and trombone.
