English-born producer and recording engineer Andy Johns, who had an impressive classic rock resume, working with the likes of the Rolling Stones, Led Zeppelin and Jimi Hendrix through the years, has died at 61. He passed away after a brief hospital stay.

The cause of death was not clear at press time, according to Rolling Stone, although guitarist Stacy Blades did state he was recently working with the producer and that he was admitted to a facility to treat an unspecified liver condition.

Andy Johns was the younger brother of producer Glyn Johns and he initially had hoped to be a bass player before taking the detour into the recording end of things. Some of the albums that litter his professional dossier include the Stones' gems such as Sticky Fingers and Exile on Main Street and Zeppelin's classics like Led Zeppelin II, Led Zeppelin IV and Houses of the Holy. Johns also was the man behind albums by Jethro Tull and Van Halen.

Johns worked with Ozzy Osbourne and Joni Mitchell after moving to L.A. in the 1970s. Some of his recent projects included albums from L.A. Guns, Godsmack and Chickenfoot.
