When YELLO was awarded the Kunstpreis der Stadt Zürich back in 1997, Claude Nobs, the legendary founder of the Montreux Jazz Festival, eulogised about the band, saying: "I worked as a cook and know about food. YELLO uses only fresh ingredients". In response, YELLO made a promise on stage that if they ever performed live in Switzerland, their first time would be at Nobs's festival in Montreux. Twenty years later, on July 12, 2017, YELLO kept their promise and performed at Montreux. Claude’s successor, Mathieu Jaton, announced the band simply thus: "Ils sont là. Ce soir. A Montreux. Pour vous!"
