Richard Barrett and Paul Obermayer have been dismantling the boundaries between improvisation and composition for some 16 years now... Full of dark undertones...it’s both humorous and disturbing at once, a gripping combination... As soon as the 45-minute masterpiece that is ULTIMATUM begins to unfold, the listener is transported into a sonic world that could come from another galaxy. Superbly crafted and incredibly inventive, ULTIMATUM holds the attention with ease. It’s music that has the formal rightness of a late Beethoven quartet...in every respect a great piece of music.
