Viennese trio Dirac are made up of Florian Kindlinger, Daniel Lercher and Peter Kutin, who are all active participants in Austria's more experimental musical circles, working in the fields of sound installation and live electronics. Emphasis falls into the latter category, and is a shining example of what can be achievedby electroacoustic free improvisation. The album opens in a slow and ambiguous fashion, taking on a minimal, soaring feel during 'This Is Your 4am Wake-Up Call', which ticks in an Oval-inspired, skipping-like fashion. It's a rather gentle exercise, but a cooly meditative introduction to the sort of sounds that'll be explored in greater depth during what's yet to come. 'Augarten' is a lowercase affair, creaking, crackling and occasionally emitting loose, disloated notes from guitar and piano. It's quiet and relies on your close attention, but its marriage of musicianly understatement and sheer otherness rewards your full engagement. Next, 'Bantu' offers a more confirmedly musical piece, glistening with processed tuned percussion and woozy, elongated tones that take on a curiously jazzy feel. The final entry, 'A Rest In Tension' is a more simplified composition, embracing the kind of organically derived drone sounds you'd hear on a Tape or Mountains record. Recommended.
