Here's a Cleveland Slovenian Style Button Box Instrumental Polka that I arranged back in the mid-90s. The A section is from an arrangement on Joe Fedorchak's "For that Old Gang of Mine" album- (with an added left hand Bass lick/ break) and I composed the B section to show off some chromatic motions that aren't typically played on diatonic button accordions in this music.
I did a full band recording (drums, bass, keyboard) of this arrangement while I was recording the "Familiar Faces in New Places" album but it was only issued on a limited edition Sampler CD for Euro-Class Music. If you're interested in hearing the full recording- it's available as a download for members of my Patreon page. (For only $3/ month or a $34 annual membership- you have access to the downloads of new and classic/unreleased recordings)
