2011, Bobby Liebling and Pentagram have been churning out widely admired hard rock/doom metal for over four decades. Within its first, this D.C. band is largely regarded as pioneering not one but two subgenres of hard rock. At the onset of the 1970's, they helped procreate a behemoth called, ´Heavy Metal`. Nine years on, they'd be planting the dark seed of what would grow to be known as ´Doom`. 2011 marks the 40th Anniversary of this American treasure and see the release of their first DVD which show a fantastic show from their concert at Deathfest 2010 in Maryland.
