Mark Dimond was one of the greatest Latin pianists of all times. Shamefully, his severe drug addiction took him out from the scene when he was around 46 years old. He began playing Piano professionally being a teenager in a sextet gathered by his later friend, Andy Harlow (Larry's brother, Buddy's son). After that he became Willie Colon's Band Pianist, from 1967 to 1970, being a key ingredient on Colon's new and aggressive sound, and setting the platform for Hector Lavoe's first steps in New York, with Colon's Orchestra. Actually, years later Dimond's was the Pianist in Lavoe's solo debut "La Voz" from 1975.
