Book excerpt: Praised as "brilliantly revelatory...a masterful work of critical journalism" (Kirkus Reviews, starred review), The Holy or the Broken is the fascinating account of one of the most-performed rock songs in history--Leonard Cohen's heartrending "Hallelujah." How did one obscure song become an international anthem for human triumph and tragedy, a song each successive generation seems to feel they have discovered and claimed as uniquely their own? Celebrated music journalist Alan Light follows the improbable journey of "Hallelujah" straight to the heart of popular culture.
