Musical hauntology conjures sounds of futures that never arrived: music that reflects on memory and the recent past, drawing on analogue instrumentation, sampling and digital processing to capture how time feels twisted in an age of endless reproduction. The Sounds of Lost Futures offers the first sustained overview of this influential British mode, tracing its emergence, cognate genres and wide constellation of media influences. It also unpacks the conceptual forces that shape it – from nostalgia and retro culture to fractured temporal experience – while covering key artists and labels such as Ghost Box, The Caretaker and Mordant Music. With a dedicated focus on audiovisual hauntology, this book provides new clarity on a musical form attuned to the strange echoes of modern life.
