Harper-Scott has produced six books, four as sole author and two as editor, and has published widely on Elgar, Wagner, Britten, and symphonic music and opera of the late nineteenth and twentieth centuries. His work has strong intersections with continental philosophy and psychoanalysis (Heidegger, Badiou, Žižek, and Lacan) and has increasingly come to espouse an explicitly Leftist perspective.
