The members of the band were Emil on saxophone, John on bass and violin, Gene on drums, and Walt on accordion.
[1] On August 28, 1957, the Matys Brothers appeared on American Bandstand performing "Muskrat Ramble" and "Crazy Street".
Later, the Matys Brothers grew to rely on their own instrumentation (Walt: the accordion, John: the bass and fiddle, Emil: the sax, and Gene: the drums).
Gene and Emil could play any instrument (you put in their hands) and began recording polka music for the Sunnyside and Select labels during the late 1950s and early 1960s.
Some of the brothers struggled, at times, to maintain normal family life due to the late hours and the demanding travel, that was a part of their profession.
