California rockers P.O.D. are suing their record label for breach of contract.
The Boom hitmakers claim executives at Tennessee-based Ino Records backtracked on a deal to pay the band an advance for its next album.
In the suit, frontman Sonny Sandoval and his bandmates allege Ino bosses were required to provide a $400,000 (£250,000) advance in November, when the group started recording the follow-up to 2008's When Angels & Serpents Dance.
P.O.D. signed with Ino in February, 2007 after parting company with Atlantic Records.
