In addition to guitar, bass and beats, he added flutes, various brass instruments and a variety of exotics.He has shared the stage with Weezer, Andrew WK, Glassjaw, Ryan Dunn and the Misfits before retiring from performing in December 2011 to battle accelerated phase bone marrow cancer.[5] In 2009, Lieberman signed a multi-album deal with Jewish indie label JDub Records,[6] taking the place of Matisyahu on their artist roster. As of the spring of 2011, Lieberman, a town comptroller by trade, was "the world’s only orthodox Jewish heavy metal musician with a record deal", according to Newsday.[7]
