This is the second release in Sub Rosa’s Invisible Architecture series and it sees two masters of the "digital bleeps" manipulation cooperate. Christian Fennesz and Mika Vanio (one half of Pansonic) worked together in this new release recorded live in Brussels at the Kaaitheaterstudio the 29th of November 1999. The slowly evolving drones of ?34 minutes 20 seconds’ are kinda chatartic and the duo build a deconstructed suite which has got two kind of treated noises: one part digital bleeps and contorted tiny instant metallic noises and the other one is made of kinda ambient sounds ... Here and there they also used buried melodies which make the suite a little more interesting. Mika Vainio’s solo piece ?32 minutes 19 seconds’ is more subtle and fades in slowly with little volcanic like explosions along with hypnotic frequencies. The piece has got less sound interruptions (while the other one was a continuous stop and go of changing noises) and it grows slowly until it explodes into chaotic pads which suddenly dive into monotonous frequencies. An interesting work which request a certain concentration into the listening: you are warned!
