Jazzclub Unterfahrt is an internationally renowned music club in Munich. On the occasion of the club’s 40th birthday, its brand design was overhauled and given an event-focused look. The event symbol developed for the club’s birthday communications is based on the number “40” in symbiotic design with a musical note. Along with this, statements on jazz have been developed, setting a new unconventional tonality to create an enjoyable and close relationship with the audience. Individual design elements reflect the need for rapid provision of information and a high level of brand recognition simultaneously. The strong contrast between the colours used highlights the high-impact appearance.
