Bonfire (originally Cacumen) is a German heavy metal band, founded in Ingolstadt, Germany in 1972. Bonfire has a unique history. Currently there are two bands who have held the name. The original group started out as Cacumen, became Bonfire and ended in 2011 as Charade. The second group began as Lessmann/Ziller, evolved into Ex and then purchased the rights to the Bonfire name, which they have used ever since.
