Gunther Dieser was a German music poster designer in the 1960s and 70s. He was born in 1930 in Kronberg. In the beginning, Kieser was a freelancer. However, after partnering with Hans Michel in 1952, they co-founded their own studio. Initial projects included designing work for the German Mail Service. This then progressed into designing for music concerts and musicians, which really helped to define his career and reputation.
Notable concerts Kieser and Michel designed for include those of Ella Fitzgerald, John Coltrane, and Oscar Peterson. After the partnership ended, Kieser continued to work as a designer for Lippmann & Rau. He produced work that was essentially displayed everywhere.
The poster design above was designed for Jimi Hendrix’s concert in 1969 and is arguably the most popular of his designs. It was extensively reproduced for other aspects of Hendrix’s shows. I personally love the unorthodox colour palette and the chaotic feel of it. Normally, I would think this design is too busy, but I think it embodies the culture of music concerts well with the high contrast and lively feel. It is very graphic.
