After more than two dozen books ranging from the history of philosophy to David Bowie, Simon Critchley has written his first novel, which connects the Renaissance mnemonic device called memory palace to, among other things, pop songs. For The Organist, Critchley provides a guided tour through the pop music that constructs his life’s memories, offering reflections on Nietzsche, krautrock, Obama, and Swedish synth-pop along the way.
