At the age of seven, RonKat's father Lester took him to a Jazz club in Grand Rapids, Michigan and asked the legendary Grant Green to let his son play percussion for a song. Reluctant at first, Green agreed after RonKat stole the show, he was asked to return 'anytime'. That began the musical career of RonKat Spearman.
