Allen Klein, American businessman and talent agent, founded ABKCO Records (born 1931)

Allen Klein was an American businessman whose aggressive negotiation tactics affected industry standards for compensating recording artists. He founded ABKCO Music & Records Incorporated. Klein increased profits for his musician clients by negotiating new record company contracts. He first scored monetary and contractual gains for Buddy Knox and Jimmy Bowen, one-hit rockabillies of the late 1950s, then parlayed his early successes into a position managing Sam Cooke, and eventually managed the Beatles and the Rolling Stones simultaneously, along with many other artists, becoming one of the most powerful individuals in the music industry during his era.

ABKCO Music & Records, Inc. is an American independent record label, music publisher, and film and video production company. It owns and/or administers the rights to music by Sam Cooke, the Rolling Stones, the Animals, Herman's Hermits, Marianne Faithfull, Dishwalla, the Kinks as well as the Cameo Parkway label, which includes recordings by such artists as Chubby Checker, Bobby Rydell, the Orlons, the Dovells, Question Mark & the Mysterians, the Tymes and Dee Dee Sharp. Until 2009, ABKCO administered Philles Records and its master recordings, including hits by the Righteous Brothers, the Ronettes, the Crystals and others. The label is infamous for its management contracts and lawsuits by its founder Allen Klein, the latter of which persisted until his death.
