Composer Arvo Part and producer Manfred Eicher have maintained their creative partnership for more than 30 years. Eicher launched ECM New Series in 1984 as a platform for Parts music, bringing the Estonian composer to the world's attention with Tabula Rasa. Since that epochal release, all first recordings of Parts major works have been made for ECM, with the composers committed participation. In this special double album, issued on Parts birthday, Eicher revisits episodes from their shared musical quest, evoking fresh associations from juxtapositions of pieces in his dramaturgical sequence, as we are invited to hear the music anew.
