Fantastic video, Albert. Thank you. If you like this music, I am sure you like that of the greatest master of the modern tango Astor Piazzolla. His classic recording "Zero Hour" is a must hear.
Orpheus10, the instrument is actually the bandoneon, not the accordion. The second link below includes a discussion with Piazzolla about the bandoneon. Very interesting stuff.
