This British businessman, music publisher, writers' representative, filmmaker and record label executive managed The Beatles while simultaneously managing the album "More Hot Rocks?".
More Hot Rocks (Big Hits & Fazed Cookies) is the second compilation album of Rolling Stones music released by former manager Allen Klein's ABKCO Records (who usurped control of the band's Decca/London material in 1970) after the band's departure from Decca and Klein. 
Allen Klein (December 18, 1931 July 4, 2009) was an American businessman, music publisher, writers' representative, filmmaker and record label executive, most noted for his tough persona and aggressive, innovative negotiation tactics, many of which established higher industry standards for compensating recording artists. 
 He first scored massive monetary and contractual windfalls 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.
