After several free improv sessions in various duo and trio formations in 2010, the four Berlin based bass players Antonio Borghini, Meinrad Kneer, Miles Perkin and Klaus Kürvers finally met as a quartet in March 2011. Ever since, they created together music on the basis of the sonic possibilities of the purely acoustic played double bass. It is crucial for the quartet, that their music is built on the diverse individualities of the involved players, but at the same time they manage to realize a unique ensemble sound.
