Rock promoter and music publisher Don Krishner has died at the age of 76. He was being treated for an infection at a hospital in Boca Raton when he died on Monday, promoter Jack Wishna, a close friend and business associate told on Tuesday.

Krishner was once called “The Man with the Golden Ear” by Time Magazine. He had helped the make-believe groups The Monkees and The Archies garner music hits and enhanced the careers of Neil Diamond, Billy Joel and the Police.

He first began in the business as a song writer. He wrote “My First Love” for Bobby Darin. However, he had more accomplishments in tapping song writing talents such as King, Neil Sedaka and Diamond.

In the 1960’s, Kirshner’s songwriters were tapped to compose music for a group built for television named The Monkees. The group became very famous in TV, as well as in the rock world with their hits “I’m a Believer” that Diamond had written.

Mickey Dolenz of The Monkees said he remembers Donnie as one of the ‘suits’ that originally came out the West coast from New York and would appear at some of the studio sessions. At first, Dolenz didn’t know what he did. Years later, he realized how Donnie had made an influence on the choice of material that his group produced and he is eternally grateful for that.

Before his death, Kirshner was the chief creative officer of Rockrena, a company that will launch this year to seek and promote talents on the internet.
