Avalancha (Spanish for "Avalanche") is the fourth and final studio album released by Spanish rock band Héroes del Silencio in 1995. It's the only album in which 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 (Lou Reed, Pink Floyd, Peter Gabriel, Alice Cooper, Kansas, Kiss, etc.) 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.
The album reached the top position in the Spanish album charts and scored positions among the top 20 in three other European countries. The video for the single "La Chispa Adecuada" was chosen as 'video of the year' at the 1996 Billboard Latin Music Awards.
