Passing away yesterday at the age of 84, Mickey Roker, the Miami-born drummer who developed on the scene in Philadelphia and who won the admiration of Dizzy Gillespie, will be remembered most besides his work with Diz, Gigi Gryce and Ray Bryant for his participation on a number of classic albums that include Herbie Hancock’s Speak Like a Child and San Francisco by Bobby Hutcherson.
