Billy Martin and Big Sam are the latest addition to the Ropeadope 10th Anniversary Celebration. These musicians will join previously confirmed performers John Medeski, John Ellis and Charlie Hunter in an old school improv-mash-up. The groove-trio Otis Grove will supply support duties.

As previously reported, the event will take place at New Yorks Sullivan Hall on June 10, benefiting longtime Ropeadope producer Scotty Hard. The producer is in the process of getting his career back in gear after being paralyzed in a car accident last year.
