Sinergy was a Finnish
metal band started in 1998 by American musician
Kimberly Goss. Aside from Sinergy, the most notable bands Goss has been involved with are
Dimmu Borgir, as keyboardist; and
Children of Bodom, where she filled in live for
Janne Wirman (keyboards) and also contributed lyrics. The idea for a "balls-out female-fronted metal band" was first formed when Goss met
Jesper Strömblad of
In Flames whilst on tour with Dimmu Borgir in 1997.
