Allen Klein

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.
