Detroit-born Jack White is always on the go, constantly reinventing himself. He has composed one of the most popular rock hymns with a guitar and a drumkit, founded two supergroups, gotten a head-start on vinyl’s comeback with his own label, and sent one of his discs into space. So, when everyone said that his latest album was one of his most ambitious works, it was quite a feat. Boarding House Reach is a radical, experimental, celebratory mass of retro-futurist funk, eighties synth, jazz syncopations and hip-hop beats. In concert, this wide-ranging work enriches a show that is already unpredictable and wild. He never decides what he’ll play in advance – he prefers to see how he feels and mix his solo songs with classics from The White Stripes, The Raconteurs and The Dead Weather. Jack White embodies better than anyone two of the guiding principles of the Montreux Jazz Festival: improvisation and spontaneity.
