Career
He was the original keyboardist for The Cure, but before that he and Simon Gallup were involved in two other bands called Lockjaw and The Magspies (aka The Magazine Spies). When Hartley and Gallup first joined The Cure, they helped drive the band in an entirely new direction with the recording of their second album, Seventeen Seconds, a much darker album than their debut, Three Imaginary Boys. Hartley also served as one of the keyboard players for the Cult Hero project
After a lengthy world tour to support Seventeen Seconds, he quit the band due to a difference of opinion with the other three members.
Since leaving The Cure, he has played with different local bands, including Fools Dance in their early stages, as well as many newer small bands in Brighton including The Icicle Thieves. He has worked at a zoo and as a labourer.
He still keeps in touch with Robert Smith.
