The World's Largest Gathering of Accordion Stars!

That's the claim made by The Las Vegas International Accordion Convention. The lineup does look good: Walter Ostanek, Art Van Damme and many more (including former Those Darn Accordions riffmeister Ron Borelli).

The big big shoooo runs June 18 to 21 at the Gold Coast Hotel in Sin City, and celebrates "the centennial of the piano accordion" (although it's not clear how they pegged that date, given the instrument's murky history).
