"It is with great sadness that I've just been informed that Bob Johnston, a great producer who worked with artists including Bob Dylan and Johnny Cash, has died aged 83.
He was behind the desk for Dylans Blonde On Blonde album in 1966, and also oversaw Johnny Cashs live records At Folsom Prison in 1968 and 1969 At San Quentin.
One of Johnstons friends confirmed the news of his death at a Nashville hospice to The Austin Chronicle: Bobs wife told me "he passed away peacefully. The grand master waved his magical wand for the last time, then disappeared off into the night."
Johnston was born in Texas in 1932 and before landing a job as in house producer at Columbia Records, he wrote tracks for Elvis Presley and Bill Haley And His Comets.
He went on to work with a range of artists, including Leonard Cohen, Simon And Garfunkel, the Byrds, Pete Seeger, Jimmy Cliff, Marty Robbins and Willie Nelson.
I had the honour of working with the great man himself . My heart goes out to his family & my prayers are with them.
The next time you listen to the work we did together, raise a glass in Bob's memory.
Rest in Peace my friend.
