"Erfolg" is the second solo album of the exceptional musician Hans Koch, released 25 years after his first solo work ("Uluru"). "Erfolg" documents Hans Koch's experimental examination of his three instruments bass clarinet, soprano and tenor saxophone. The pieces are state of the art instant composing and sound research.Besides numerous collaborations - in the trio Koch-Schütz-Studer, with musicians like Barry Guy, Cecil Taylor, Han Bennink, Fred Frith, Urs Leimgruber and many others - Hans Koch works intensely as soloist. Inspired by electronic & acoustic, written & improvised music he investigates the possibilities of a solo reeds player on stage and in the studio.He has recorded this rather lab like work on his musical language material over years. The recordings grew, transformed and renewed themselves, were dismissed and re-recorded over the time. What emerged from this working method was a process-in-progress which shifted, affected and re-drafted its origin steadily.On the album at hand this process comes to its conclusion. Embedded in four subtle pieces called Feedback we find eight pieces, each of them dedicated to one of Koch's instruments. They examine a particular circumstance, their own sound. With a minimalistic approach they create rich, rough and lively soundscapes and scenarios."Erfolg" is an extraordinary documentation of a consequent occupation, of an impressive artistic process. A process Hans Koch chose an ending for by publishing his second solo abum. 'Uluru' is continued, it has a musical counter piece, an answer. Never the less, the searching movement will go on now that Hans Koch made way for new musical experiments.This release is packed in a hand stamped cover. Each of the 400 copies is unique and serially numbered.
