In the 1960s, within the larger context of the civil rights movement and the burgeoning counterculture, the blues changed from black to white in its production and reception, as audiences became increasingly white. Yet, while this was happening, blackness--especially black masculinity--remained a marker of authenticity. Crossing color lines and mixing the beats of B.B. King, Eric Clapton, and Janis Joplin; the Newport Folk Festival and the American Folk Blues Festival; and publications such as Living Blues, Ulrich Adelt discusses these developments, including the international aspects of the blues. He highlights the performers and venues that represented changing racial politics and addresses the impact and involvement of audiences and cultural brokers.
