Carmine Appice: "John and I were testing out some new Ludwig stands while playing the Kinetic Playground in Chicago. By the end of the night, we had both broken the stands so we gave them back and said: "They're gonna need  to be a lot stronger, we broke them." You should have seen the look of shock on the faces of the people from Ludwig!"
