吉他：Oren Ambarchi 桌台电吉他：Keith Rowe 演绎选自《Treatise》第53、58、168及169页 2009年2月8日录制于阿姆斯特丹Bimhuis现场 Cornelius Cardew的《Treatise》是一部创作于1963至1967年间的193页图形乐谱，彼时他正与即兴团体AMM合作。这部作品以精密设计的线条、几何形态与符号构成图谱记谱法，旨在动摇传统作曲的边界——音高、音色、时值乃至乐器配置与演奏人数，都交由演绎者自行制定规则与手段。Keith Rowe与Oren Ambarchi对其中四页乐谱的诠释，堪称最具震撼力的演绎之一。两位音乐家从吉他出发，开拓出全新的声响境界。Rowe自1960年代便彻底背离传统爵士，在AMM中重新定义了吉他的角色，惯于将乐器平置桌面，利用弹簧、风扇、办公用品及电子设备操控声响。Ambarchi（亦活跃于Sunn O)))、Menstruation Sisters及Burial Chamber Trio等团体）则擅于将吉他声淬炼为幽暗的音律图景。Cardew或许是英国最具现实意义的当代作曲家。1950年代末，Karlheinz Stockhausen为其音乐造诣所叹服，邀他参与科隆具有历史意义的Kontrefestival系列音乐会。1960年在达姆施塔特，Cardew邂逅John Cage、David Tudor与Walter Marchetti等人，Cage的实验手法深刻启发了他，促使他于1969年创立Scratch Orchestra——这个由专业与业余表演者轮换组成的大型集体即兴乐团，以共同实验精神成为20世纪先锋文化中极具说服力的集体创作之一。Guitar - Oren AmbarchiTabletop - Keith RowePages 53, 58, 168 & 169Recorded live at Bimhuis, February 8th, 2009Recorded b Ron Ruiten, mastered by Giuseppe IelasiThanks to Takehisa Kosugi, Earware Fest, Biel & Juha van 't ZelfdeCornelius Cardew's opus magnus Treatise is a 193 page graphic score written between 1963 and 1967 while he was performing with the improvisation group AMM. The score's graphic notation, with its intricately devised graphic lines, shapes and symbols was intended to question the limits of compositional practice. Decisions concerning pitch, timbre and duration, along with the choice of instruments and the number of performers, are left entirely to the discretion of those willing to devise the rules and means for its performance. This realisation of 4 pages from Treatise by Keith Rowe (Tabletop Guitar) and Oren Ambarchi (Guitar), possibly the most powerful ever acheived, was recorded live at Bimhuis in Amsterdam on Feb 8th 2009. Rowe and Ambarchi use the guitar as a point of departure for completely new techniques and sound environments. Already in the 1960s Rowe made a radical departure from traditional jazz, redefining the guitar in the British collective AMM. He prefers to lay the instrument on the table to manipulate its sound with springs, fans, office appliances and electronics. Ambarchi, also in Sunn O))), Menstruation Sisters and Burial Chamber Trio, predominantly mould guitar sounds into dark sonic patterns. Cornelius Cardew might be considered the most relevant contemporary composer from Great Britain. In the end of the 1950s Karlheinz Stockhausen was very impressed by Cardew's abilities as a musician and his knowledge of new music and invited him to partecipate to the historical Kontrefestival concerts in Cologne (an important pre-fluxus event). In 1960 Cardew was at Darmstadt were he met John Cage, David Tudor and among others Walter Marchetti. Cage's experimental techniques were very inspiring for Cardew who, in 1969 founded the Scratch Orchestra, a large, rotating group of professional and amateur performers committed to collective experimentation which might be considered as one of the most convincing collective experiments in the history of 20th century avant-garde culture.
