Project Earth – The Blue Chapter

The idea for Project Earth began on a train in Germany in 2018. We were on our way to the Sendesaal Bremen to record the Iris Trio’s first album, Homage and Inspiration, and Florian Hoefner, Christine’s partner, was along for the ride with their one-year-old son Max. We were brainstorming next projects for the trio, and the three of us unanimously turned to Florian, wondering if he might consider writing for the ensemble. Fortunately for us, he agreed right away. We were thrilled at the prospect of stepping outside our classical realm and playing music inspired by Florian’s jazz language.
