'After their first successful collaboration Further Consequences of Reinterpretation (premiered in May 2003 at the Goethe-Institut in Lisbon, released as a CD album by the Portugal-based label Crónica), and the project's appendix release entitled Product, the sound artists Paulo Raposo and Marc Behrens have created a new dynamic sound work entitled HADES. HADES is based on sound recordings made aboard Lisbon ferries and at the quays of Cais do Sodré, Trafaria and Cacilhas 2001-2005. Both artists had initially set out to record independently, being fascinated with the sounds of the ship hulland landing gear, as well as with the actual passage on the river, which gives a magnificent (maybe the best) view on large parts of the old city of Lisbon. During the course of the work which took three years to complete, some more precisely directed recordings were made together. Understanding the actual crossing as a symbolic passage, and once it was reduced to sound and memory, it became associated to the crossing of the mythic river Styx to enter Hades, the ancient Greek underworld. As the different sound recordings provide the artists with very diverse material (for example low frequencies from the ship's hulls and motors, high frequencies and beats from the gates at Cais do Sodré), they understand the composition as hovering on the delicate borderline between a soundscape portrait and a multi-strata arrangement, in which things happen parallelly, and individual layers move on more than one path simultaneously. In the opinion of and-OAR, HADES is not only one of the strongest works to surface from either artist, a-O will go out on a limb to state that it could very well set a new precedent of quality for collaboration work of it's ilk. Needless to say, a-O is highly honored to be releasing it. Please give it a very attentive listen. Especially in headphones!'
