Schwyzerörgeli
The Schwyzerörgeli is a squeezebox diatonic button accordion used widely in Swiss folk music. This looks like a brand new instrument, expertly played by Albert at the Swiss Market.
(Pushes all the right buttons for nostalgia.)

Albert and Schwyzerörgeli
My dad was a big fan of accordion music. Not really my cup of tea, but I did visit a festival a few years ago and met a few of the musicians.
