The singer, vocal acrobat and composer Andreas Schaerer is one of the busiest Swiss vocalists and he impresses not only with his expressive voice - covering an extraordinary range - but also employs a seemingly infinite variety of vocal sounds. He tours regularly with various groups and has worked with, amongst many others, Bobby McFerrin. Bänz Oester is an extremely perceptive and profound bassist whose boisterous style one can't but love and he has worked with jazz greats such as Dewey Redman, Joe Lovano, Vienna Art Orchestra, Michael Brecker, Chris Potter and Erik Trufazz, to name a few. Schaerer and Oester tour as a duo, extracting a seemingly limitless range of jazz references and styles and their speciality is composition on the instant, with fascinating, refreshing results. Thus, fittingly, tonight they are joined by two equally creative musicians - from Cape Town Mark Fransman (sax, piano) and from Paris Deborah Tanguy (vocals).
