Howlin' Wolf performing at the American Folk Blues Festival with Hubert Sumlin on 2nd guitar, Introduced by Nina Simone.
The American Folk Blues Festival was a music festival that toured Europe as an annual event for several years beginning in 1962. It introduced audiences in Europe, including the UK, to leading blues performers of the day such as Muddy Waters, Howlin' Wolf, John Lee Hooker and Sonny Boy Williamson, most of whom had never previously performed outside the US. The tours attracted substantial media coverage, including TV shows, and contributed to the growth of the audience for blues music in Europe.
