LAS VEGAS (AP) - A business associate and close friend in Las Vegas says rock promoter Don Kirshner has died of heart failure in a Florida hospital at age 76.

Promoter Jack Wishna tells The Associated Press that the man Time magazine once dubbed the "Man With the Golden Ear" died Monday at a Boca Raton hospital where he was being treated for an infection.

Wishna calls Kirshner an icon who touched more lives in the music industry than anyone else.

Kirshner was behind "Don Kirshner's Rock Concert" in 1972, and gave national exposure to musicians including Billy Joel and The Police.

He also boosted careers of comics including Billy Crystal, Arsenio Hall and David Letterman.

Kirshner was chief creative officer of Rockrena. It's a company launching this year to find and promote talent online.
