Minnear received a classical music education at the Royal Academy of Music, with a degree in composition.
Contributing to the band's success as one of the composers and arrangers, Kerry, unlike most of the keyboardists of his time, chose to create natural sounds from his keyboards. Like the other members of Gentle Giant, he is quite adept on a number of instruments including the cello, drums, guitar,bass, idiophones, recorder, theremin, and tympani.
He now lives in Solihull (West Midlands) with his wife Lesley and has three children, Sally, Sam and Susie. Still part of the Gentle Giant franchise, he also composes for film and television.
In the years since the disbanding of Gentle Giant, Minnear has been a teacher and a church musician, since he is a Christian. He and his wife Lesley own Alucard Music, which releases Gentle Giant CDs and DVDs.
