Grant may not play an instrument but he is one of the greatest "jazz musicians" in the world. His instrument, food. Martin Kastner is a genius, he is a sculptor / designer whose medium is the table top. He seeks to constantly redefine how food is consumed. He grew up outside Prague and carries with him the essence of that city. He is reflective and when he talks his words have gravitas. (Did I just use the word gravitas) - damn, but it's true.
