My friend Michael Heller , a great musician whom I met at the Harvard Music Department , led in 2011-2012 an exciting year with the Dudley House Jazz Band. I already told you about his 2010 project around Mary Lou Williams' music ; he went further in 2011-12 when he invited Dave Liebman and Lewis Porter to perform with the band in Paine Hall. Michael released videos of the concert. Here is a favorite, Hiroshima Memorial : Creation Creation lied at the core of this artistic project, with improvisation, creative arrangements, and the world première of a concerto for Dave Liebman and symphonic orchestra, composed by Lewis Porter in what we could call the Third Stream tradition of mixing genres. An excerpt from the program, where composer Lewis Porter presents his Liebman concerto .
