Jack Grace (born 1968, Brooklyn, New York) is an American songwriter, bandleader, radio host and actor based in New York. Jack contributed music to the cult films Super Troopers and Beerfest. In radio, Jack has been a commentator on PRI's The Takeaway beginning in 2008 and is a fill-in co-host for Sirius/XM's Freewheelin'. Jack studied acting at NYU and didn’t pick up a guitar until he was 18. His theatrical background made him extremely comfortable on the stage, to which his spirited live performances are a testament. An icon in New York City, Jack is often known as The Martini Cowboy, the title of his 2008 C.D. release on Radia Records.

Jack formed his first band in 1993 in Boulder, CO. Steak was an experimental, Zappa-flavored 4-piece band that officially disbanded in ’99. Jack began working with a revolving group of musicians even to this day. Functioning more like a jazz bandleader, he has a main cast of characters but keeps two to three drummers on call for recordings and gigs. The band members come from all walks of life: jazz, rock, country and, well, other. Bassist, vocalist and wife Daria (Melomane, Pre-war Ponies, The (N.Y.) Moonlighters & God Is My Co-Pilot) keeps the rhythm going with the rotating drummers, Russ Meissner, Jason "J-Bird" Bowman and Bruce Martin (Tom Tom Club).
