RZA and his brother are accused of never paying producer 4th Disciple.

(AllHipHop News) Wu-Tang Clan frontman RZA and his brother are being sued by one of the group's longtime producers.

4th Disciple filed a lawsuit against RZA, born Robert Diggs and his brothers, Mitchell "Divine" Diggs.

The producer, whose credits include records for the main members of the Wu-Tang Clan, as well as affiliate groups like Killarmy, Sunz of Man, Killah Priest, Gravediggaz, and others.

According to the producer, he has been cheated out of millions in royalties since he signed a lopsided agreement with the brothers back in 1993.

"Plaintiff has never received an accounting statement nor any royalties under either the Production Agreement nor the Publishing Agreement, he has no idea what Recordings are

being claimed by Defendants under the Production Agreement nor what Compositions are being claimed under the Publishing Agreement," 4th Disciple claims in his lawsuit.

"We reached out several times to RZA and his brother Mitchell, through their longtime attorney, and they refused to address the situation," 4th Disciple's lawyer Kevon Glickman told AllHipHop.com.

4th Disciple also claims he has never received accounting for any of his productions over the course of the last 25 years.

"Its a shame that with all of the success of the Wu Franchise, it will take a lawsuit to force the Diggs brothers to face their contractual responsibilities," his lawyer Kevon Glickman added.

4th Disciple is seeking a full accounting oaΩ, in addition to at least $500,000 in damages.
