Tributes: Pulse

'Tributes-Pulse' is a collaboration between American filmmaker Bill Morrison and Danish composer and percussionist Simon Christensen. Christensen originally conceived of the project as a tribute to four American composers, Charles Ives (1874-1954), Conlon Nancarrow (1912-1997), Steve Reich (b. 1936), and Trent Reznor (b. 1965).
