'There have been no book-length studies of the Conductus until Discovering Medieval Song, expertly written by the foremost authority on the genre, and on music of the so-called ars antiqua more generally. Covering everything from the Conductus's complicated relationship to the liturgy, to its ties with contemporaneous genres such as the motet and organum, Discovering Medieval Song is both the first comprehensive study of the genre and a nuanced examination of thorny issues of performance and musico-poetic relationships. Its broad scope should not confuse readers - this is not merely a reportorial survey. Rather, the book offers new insights into performance, form, and the inter- and intratextual poetics of the Conductus, and includes new discoveries and information on sources and individual works. This will be the book to consult on the genre for many decades to come.' Mary Channen Caldwell, University of Pennsylvania
