Listen to what's next! It's about pricked ears, quick-witted reactions - and instant composition. With virtuosity and playfulness, the experienced Swiss Jürg Solothurnmann and Dieter Ulrich are teaming up with the younger colleges Beat Unternährer and Christian Hartmann. Roguishness is the fifth invisible member. With their spontaneous flashes of wit, the players often blindside even themselves. The jazz tradition and other influences are aired and loosened with a free-rambling intuition.
