<P> The Martin Luther King Jr . Memorial was dedicated in 2011 . The centerpiece for the memorial is based on a line from King's "I Have A Dream" speech: "Out of a mountain of despair, a stone of hope ." A 30 feet (9.1 m) - high relief of King named the "Stone of Hope" stands past two other pieces of granite that symbolize the "mountain of despair ." </P> <P> In August 2012, the Dutch DJ and producer Bakermat released the single "One Day", which consists of an integrated sample of the speech . The re-release in 2014 became a hit in several European countries . </P> <P> On August 26, 2013, UK's BBC Radio 4 broadcast "God's Trombone", in which Gary Younge looked behind the scenes of the speech and explored "what made it both timely and timeless". </P> <P> On August 28, 2013, thousands gathered on the mall in Washington D.C. where King made his historic speech to commemorate the 50th anniversary of the occasion . In attendance were former U.S. Presidents Bill Clinton and Jimmy Carter, and incumbent President Barack Obama, who addressed the crowd and spoke on the significance of the event .
