Stephen Lloyd, Constant Lambert: Beyond the Rio Grande (Boydell, $64). The first full-length biography of the jazz-influenced composer-conductor-critic who wrote Music Ho! and was–or should have been–England’s Leonard Bernstein. If you only know him as the model for Hugh Moreland in Anthony Powell’s A Dance to the Music of Time, this superbly thorough biography will tell you the whole sad story (TT).
