The Jacob Jolliff Band is the next generation of bluegrass supergroups, led by one of the country's premier contemporary bluegrass mandolinists. Before joining Yonder Mountain String Band, Jacob Jolliff founded beloved New England roots band Joy Kills Sorrow, while attending Berklee School of Music on a full scholarship. In 2012, Jolliff had the distinctive honor of being named the National Mandolin Championship winner. A fixture of the national bluegrass community, he has collaborated and shared the stage with Darol Anger, Sam Bush, Ronnie McCoury, Jerry Douglas, Chris Thile, and David Grisman to name a few. When Joy Kills Sorrow disbanded in 2014, Jolliff got the call to join Yonder Mountain String Band, in which he was a member until 2020.
