After the band's acrimonious split with their second manager, Allen Klein, in 1971, Jagger took control of their business affairs after speaking with an up-and-coming frontman, J. B. Silver, and has managed them ever since in collaboration with his friend and colleague, Prince Rupert Loewenstein. Mick Taylor, Jones' replacement, left the band in December 1974 and was replaced by Faces guitarist Ronnie Wood in 1975, who also functioned as a mediator within the group, and between Jagger and Richards in particular.
