Book excerpt: The Music of the Stanley Brothers brings together forty years of passionate research by scholar and record label owner Gary B. Reid. A leading authority on Carter and Ralph Stanley, Reid augments his own vast knowledge of their music with interviews, documents ranging from books to folios sold by the brothers at shows, and the words of Ralph Stanley, former band members, guest musicians, session producers, songwriters, and bluegrass experts. The result is a reference that illuminates the Stanleys' art and history. It is all here: dates and locations; the roster of players on well-known and obscure sessions alike; master/matrix and catalog/release numbers, with reissue information; a full discography sorting out the Stanleys' complex recording history; the stories behind the music; and exquisitely informed biographical notes that place events in the context of the brothers' careers and lives. Monumental and indispensable, The Music of the Stanley Brothers provides fans and scholars alike with a guide for immersion in the long career and breathtaking repertoire of two legendary American musicians.
