I got an email today about a fun little holiday album by Stylophonic Workshop called "Christmas on the 350s." With just five short songs, the whole thing only runs about seven minutes. But it's seven delightful minutes of nostalgia, kitsch, and some excellent musicianship. I promise it will make you smile.
All the sounds came from a vintage Stylophone 350s except for the percussion, and it really showcases the strengths of the 350s when played by a skilled and creative performer. Give it a listen on Spotify. It's also available as a playlist on YouTube.
If it inspires you to play some holiday music on your own 350s, there is Stylophone sheet music of German Christmas carols on the last couple of pages of the .pdf document at this link.
