A record producer claims in court that heavy metal band Five Finger Death Punch reneged on a contract to record a greatest hits album, reports Courthouse News Service. Prospect Park sued Zoltan Bathory and his three bandmates on April 21st in Superior Court.

The producer claims, among other things, that three members of the band are "shamelessly attempting to cash in before the anticipated downfall of their addicted bandmate."

"This lawsuit is about the creative process outlined in the agreement and the rights of both parties to have involvement to ensure the best product," Prospect Park's attorney Michael Taitelman told Courthouse News in an-email. "The band and its reps want to bypass that process, for no reason other than short term gain."

Formed in Las Vegas in 2005, Five Finger Death Punch is named for a martial arts maneuver from the 2003 movie Kill Bill. Their first three albums went gold; their songs include "Wrong Side of Heaven," "Lift Me Up," and "Wash It All Away."

The co-defendants are Ivan Louis Greening aka Ivan Moody, Jeremy Spender Heyde aka Jeremy Spencer, and Thomas Jason Grinstead aka Jason Hook.

Prospect Park says: "Regrettably, with the encouragement of their entertainment lawyer and business manager, the members of FFDP have unequivocally repudiated their contractual obligations to permit Prospect Park to determine the recording elements of a new record and a greatest hits record. In doing so, the members of FFDP are shamelessly attempting to cash in before the anticipated downfall of their addicted bandmate."

Prospect Park says the band signed a four-album contract in December 2012, with the first set for release in April 2013. Recording for the fourth album was to start this June.

When Prospect asked the band to deliver two new masters for a greatest hits record, the band refused and insisted on recording it for a different producer out of concern for lead vocalist Ivan Moody, according to the complaint.
