Bono and the Edge released an acoustic version of U2’s “Sunday Bloody Sunday” to coincide with the 50th anniversary of the titular Bloody Sunday massacre.  Sunday Blood Sunday, the opening track on the band’s landmark 1983 album War, was inspired by the Bogside Massacre, which took place on Jan. 30, 1972, when British soldiers shot 26 unarmed civilians during a protest march in Derry, Northern Ireland, ultimately killing 14 people. The black-and-white performance video is intercut with footage from the massacre; you can watch the performance – here.

U2 released War on Feb. 28, 1983. The LP became the band’s global commercial breakthrough, topping the U.K. charts and reaching No. 12 in the U.S. The album sold more than 11 million copies worldwide.
