Avalancha is the fourth and final studio album released by Spanish rock band Héroes del Silencio in 1995. It is the only album in which Mexican guitarist Alan Bogulavsky plays as a full-time member of the band. It is to date their last studio recorded album. It is considered a turning point in the Rock en Español movement of the 90's and a classic in its own right. It was produced by Bob Ezrin and recorded mostly in different studios in the Los Angeles area. It was followed by a very successful 18-month world tour after which the band went on hiatus until the announcement of a 10 date world tour in early 2007.
