I have a tape called The Father Tunes It is by Richard Koski Playing 54 old time Finnish-American and Finnish dance tunes on the 2 row button accordion.
Richard learned these tunes from his father who also played the accordion.Richard fearing that a lot of the old tunes were not being played and that there was a chance that many would be lost,decided to record all that he could in order to assure there survival. This was a low key project and consequently the sound is not the best but I found it to be a great learning tool for those learnig to play the accordion and for learning Finnish dance tunes. As for Richards playing : He never misses a beat or a note.
