The innovative acoustic free improvising ensemble Polwechsel, bridging contemporary music and free improvisation in ways that sound deceptively electroacoustic and comprised of Michael Moser on cello, Werner Dafeldecker on double bass, and Martin Brandlmayr & Burkhard Beins on cymbals & percussion, are joined by Klaus Lang performing on the church organ of St. Lambrecht's Abbey.

Only their 3rd album since 2005, the trio of Phil Durrant (modular and software synthesizers), Bertrand Denzler (tenor saxophone) and Burkhard Beins (percussion and objects) went into the studio in Berlin to record four tracks that bring the distinct skills of each player into focus while accentuating the tremendous concentration and interplay each brings, a real achievement.

"Fracture Mechanics" is the scientific study of cracks in any material, an apt title from these European experimental innovators--Burkhard Beins, Lucio Capece, Martin Kuchen, and Paul Vogel--pulling back the curtain on process and creating an impressive album crossing acoustic and electronic improv, organized sound, and inexplicable interaction; recommended.

Three impressive works of electroacoustic improv from the trio of Serge Baghdassarians (mixer, delays, electric guitar), Boris Baltschun (computer, sampler) and Burkhard Beins (percussion and zither), brooding and concentrative sound that unfolds slowly in detail and color.

Book and 2 CDs documenting a 2010 concert and sound installation by Carsten Seiffarth and Michael Moser, with Polweschsel & guests (Burkhard Beins, Axel Dorner, &c) performing the concert.
