Soft rock band The Black Crowes are suing Lloyd's of London.
The Atlanta group are claiming Lloyd's failed to pay out an insurance policy, which covered a tour with guitarist Jimmy Page last year.
The Led Zeppelin guitarist became ill, and the concerts were cancelled.
But The Black Crowes, whose first album was “Shake your money maker”, has filed a writ in Los Angeles against Lloyd's.
The band says it has not received any compensation for “the great financial loss” of cancelling the tour and is seeking undisclosed damages.
It said: “Lloyd's has embarked on a malicious course of conduct that threatens the livelihood of The Black Crowes.”
The writ adds that Lloyd's put “its own self-interest ahead of the rights and needs of its customers.”
It is thought that the dispute is over the amount of money insurers agreed to pay. Independent broker Robertson Taylor originally placed the risk at Lloyd's.
