If you want sexy accordion music, see if you can get hold of the recordings called "The Tango Project" which were issued by Nonesuch as (gasp!) vinyl LP's in the 1980's. They were so good, perhaps they are now available in another form.

There is actually a college-level program in accordion at the University of Missouri in Kansas City. I believe it is the only one in the world. The department has to submit to constant harrassment of the form you are now enduring from certain puerile Mudcatters, but nonetheless it soldiers on.
