The final instalment in LA producer Daedelus’ End of Empire trilogy, following 2010’s Righteous Fists of Harmony and 2014’s The Light Brigade, turns its gaze upon the Second Boer War (1899-1902), between Great Britain and two Afrikaner states, and the many people of colour caught between competing colonial ambitions. Despite the scale of the topic, it’s a contemplative, mournful album of slow-moving ambient music, in which unsettling electronic drones and blood-curdling noise are shot through with South African trumpeter Lee Thomson’s doleful horn. Even listeners with only the fuzziest grasp of history will pick up on the overwhelming sense of tragedy. (The title of the opening “Deep in Concentration” is not just a reference to the song’s meditative mood, but also to the role that concentration camps played in the conflict.) Intense, moving and wildly inventive, The Bittereinders is a masterpiece of electronic composition, and confirmation that Daedelus’ vision extends far beyond the beat-music scene that birthed him.
