德國城市曼海姆（mannheim）擁有悠久且重要的音樂歷史，為了慶祝建城400年，alva noto (carsten nicolai) 與坂本龍一受邀與古典音樂團體ensemble modern合作，舉行一場多媒體演出。作品「utp_」為utopia一詞的縮減，暗示著未來仍有延伸的空間，似乎以Raster Noton廠牌典型手法詮釋了城市的結構，並點出曼海姆創建時被設定為一「完美城市」的構想。音樂上除了延續alva noto和坂本之前合作，融合電子與鋼琴聲響之風格，也因為有了古典樂團的加入，而產生更寬廣可能性。這次精彩演出最後收錄在這套特別的專輯中，裡面包括CD、現場演出搭配之影像的DVD、全彩手冊、總譜以及創作過程的預演紀錄。
on the occasion of the 400th anniversary of the city of mannheim alva noto (carsten nicolai) and ryuichi sakamoto were invited to develop an audio-visual performance together with ensemble modern. the concept of the arising piece named utp_ is derived from the rasterized structure of mannheim (build as an ideal city in the 17th century) and also paying reference to the musical history of the city.
the result of the collaboration like the former projects of alva noto and ryuichi sakamoto - vrioon (2002, r-n 50), insen (2005, r-n 65) and revep (2005, r-n 72) - is a synergetic mixture of electronic and natural sounds, that is expanded by the potential of the classical instruments of ensemble modern. utp_, the title of the new composition is deduced from the term utopia and hence describes an approach that leaves space for further extensive associations.
the release consists of an audio cd, a dvd, a full colour booklet and the score. the dvd contains the utp_ concert movie and a utp_ ‘try-out’ to document both the developing process of the piece and the final result.
