This is the ultimate guide to two musical styles that have fundamentally influenced popular music. Divided into eras from the Early Years, then decade by decade to the Contemporary Era, learn about the development of this music from its 19th-century African-American roots up to the present day. Each decade has a Sounds & Sources discussion before introducing the Key Artists of the time and A-Z's of lesser artists. A section on Styles is also included, which covers jazz styles from Ragtime to Bebop and blues styles from Texas Blues to Rhythm & BLues. A section on instruments, a glossary and evocative photographs complete the comprehensive experience. Whether a fan of Duke Ellington, Billie Holiday or Ray Charles this is the book for you.
