Metamorphosis is the third compilation album of The 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. Released in 1975, Metamorphosis centres on outtakes and alternate versions of well-known songs recorded from 1964 to 1970. (More from Wikipedia)
The Beatles’ somewhat anti-capitalist stance over this period is hardly driven by some sort of Marxist-Leninist tendencies as the band’s detractors might imagine, but it is rather a natural reaction to the scandalously brutal plundering of royalties from even top recording artists that had become routine among recording industry practitioners for decades. As one of the most egregious examples, one of the Rolling Stones’ managers, Allen B. Klein tricked the band into signing over the rights to all of the music that they had recorded (through 1971) with Decca Records. (The Stones were Decca’s lucrative consolation prize when they passed on signing the Beatles). Klein’s label, ABKCO Records is frequently encountered on Stones records, including one of their rarest albums, Metamorphosis.
