Don Hunjadi grew up regularly watching his father, Dick Hunjadi, perform on stage as the drummer with Milwaukee polka great, Louie Bashell. Although he started playing trumpet in the fifth grade, by age 14, Hunjadi started playing bass guitar and within a year became the bass player with the Joey Klass Band — again alongside his father who played drums. When he was 17, he had his first opportunity to enter a recording studio when he went to Bright Productions, owned by polka great Roger Bright, to record First Klass with the Joey Klass Band. In addition to playing, Hunjadi co-owns a recording studio, and has recorded over forty bands.
