Have fun playing along with records! Great way to have fun with music and your preferred instrument, no matter the level of your proficiency.
As I'm sure you know, Piazzola does not play the accordion; he plays the bandoneon, a cousin of the accordion with only buttons and no piano keyboard. Subaruguru, if you haven't heard Piazzola's music, check it out. I think you'll change your mind about this unfortunately maligned instrument. His "Zero Hour" recording is acknowledged to probably be his greatest, incredibly passionate stuff.
Dekay, one of my favorite "The Far Side" by Larson cartoons shows two scenes. One is a long line of recently departed approaching the pearly gates, where St. Peter is welcoming each soul and handing each one a harp. The other scene is a long line of recently departed approaching the gates to hell, where Satan greets each one and hands each an accordion.
