Nice video. Accordion is very appreciated in countries who knows and uses the instrument in their styles (Brazil, Poland, Mexico, Russia...). But if people dont know, they get it as something weird, nostalgic at its best. It shares the same fate with piano and organ in a symphony orchestra, it could be used as solo but not as a part of it (maybe they could call you sometimes as guest) which doesnt get you a long term job there. I m not sure too many rock or pop group uses it (I thought these were special examples and according to country popularity of the accordion or they just wanted to be interesting). Being too much versatile is very useful as solo and in folk music, but I m not sure every music group will like you with these abilities. Accordion is not a classical music instrument originally because its been invented later. Being similar to organ, its been successful in solo works though. Bach for example. But we can still debate that. As I heard, accordion is the hardest to record the sound because every note is sounding from a different place, makes it a 3D sound output with basses especially, sound engineers dont like that much. There are also people hate the accordions buzzy sound although we dont take it like this, thats maybe one of the reasons of digital accordions.
