Latin band Los Lobos on their success in US

With hits such as La Bamba and almost 40 years of touring non-stop, the Latin band Los Lobos has a lot to look back on.

In the late 1970s Los Lobos, originally a rock band, realised they could not leave behind their roots and started to incorporate traditional Mexican elements into their repertoire. It led them to sustained success in the US. Now they are trying to break into musicals.

Louie Pérez, one of the group founders, told their story to Valeria Perasso, from BBC Mundo.
