The Rise and Fall of the Broadway Musical

From soaring divas to growling rockers : how changes in singing forged and felled the show tune ; How mavericks, highbrows, and enlightened collectivism invented the book and lyrics and tweaked the music ; Revolutions in Broadway rhythm : how the rock groove decomposed the musical and dismantled the fourth wall ; The loudspeakers are alive with the sound of music : how electronics trumped the artful acoustics of Broadway ; Wagging the musical : how director-choreographers co-opted a writer's medium ; The age of McMusicals : vaudeville redux.
