For the 1967 edition of the American Folk Blues Festival, Kieser decorated an acoustic guitar with vibrantly hued, carved filigree and beads. Two roundels feature colorized photographs of Black figures (the one at the far right might be the guitarist Hubert Sumlin, who performed with Howlin’ Wolf in the 1964 iteration of this concert) sourced from designer Günther Kieser’s large library of reference images. The upper-right curve of the guitar incorporates the phrase “born down south, the Blues went north; blues everywhere.” While this statement essentially summarizes how the genre spread from the Southern United States to the North, it also parallels the realities of the Great Migration, a period from the 1910s to 1970 when approximately five million Black Americans moved from the rural South to the urban North, bringing their musical culture with them. Lippmann + Rau used this phrase as the official tagline of that year’s concert tour. As blues performers moved into more urban areas, the clubs they played in were more crowded. This ultimately led many of them to adopt the electric guitar as their primary instrument, changing the sound of blues forever. Kieser, however, always favored the acoustic guitar in his posters for the series. The 23 stops of the festival in October indicate how popular this annual event had become; it started in Sweden and moved through West Germany, Denmark, Finland, the Netherlands, Belgium, Switzerland, and France before ending with five stops in England. The tour was further extended within the United Kingdom that month as part of “Big City Blues,” an established concert series in larger British cities.
