Best known as a side project of Mando Diao members Björn Dixgård and Gustaf Norén, Caligola was actually founded as a network of artists in Stockholm during the '70s. Dixgård and Norén joined the collective in 2008 to work on the video "Sting of Battle," which was released in December 2011. Together with drummer Oskar Bonde (from Johnossi), singer Agnes Carlsson, German DJ Paul van Dyk, and Swedish hip-hop producers Masse and Salla Salazar, they recorded the 2012 album Back to Earth, which entered the German charts at number ten, while the album's first single, "Forgive Forget," reached number two on the German singles charts. Caligola also appeared on one track of Paul van Dyk's album Evolution ("If You Want My Love"). ~ Christian Genzel
