Members of the rock band Poison claim their recording label has consistently underpaid royalties to the group throughout their career, according to a lawsuit.

The suit, filed yesterday (June 18) against Capitol Records and EMI Music Marketing, says the companies breached contracts with the band by improperly categorizing certain record sales and miscalculating everything from producer royalties to foreign taxes.

According to the band’s lawsuit, they signed a contract with Enigma Records in 1986, which later transferred control to Capitol Records.

A representative for Capitol and EMI did not immediately return a phone message seeking comment today.

Poison claims it tried to audit the band’s records kept by Capitol, but the firm didn’t fully cooperate. The band stated in its lawsuit that it cannot determine how much money it is owed and asked a judge to order Capitol Records to allow a full accounting review of the band’s records.
