Coilbox is a metal/numetal band from Madrid that formed in 1998. They, along with other influential Spanish bands such as Hamlet have made their mark playing big festivals such as FestiMad. Their first proper album "13", was released in 2002, and they steadily drifted away from their numetal roots into heavier territory, culminating in their second album, "The Havoc", in 2004. The shift in sound was due, in part, to Frederik Nordstrum's (well known producer in European metal) producing/mixing credits on the album. Currently this album has not been picked up for distribution outside of their home country, instead the band plays to a dedicated fanbase, and uses the internet as a means of garnering word-of-mouth international recognition.
