If there is one piece of liturgy that screams "Jewish Rock," it's Mi Chamocha.  This track captures the joy of freedom in its rock beats, and the melody is catchy so the words are not cumbersome.  The song started as a guitar groove in the URJ Kutz Camp lobby in 2003, but the verses didn't come together for another year.  Nevertheless, the song does not feel forced; it is naturally expressive.
