Kasper T. Toeplitz is a French composer and musician of Polish origin, born in 1960. He lives in Paris.
He has worked with academic research organizations, such as GMEM, GRM, IRCAM, and Radio-France, as well as with experimental musicians, such as Éliane Radigue, Zbigniew Karkowski, Dror Feiler, Tetsuo Furudate, Phill Niblock and Art Zoyd . Citing Giacinto Scelsi and Iannis Xenakis as influences, his early work was mostly written for traditional instruments. He received several prizes and distinctions for these works: 1st prize in composition for orchestra at the festival of Besançon, 1st prize in the Opéra Autrement/Acanthes competition, Villa Médicis Hors-les-Murs in New York, prize Léonard de Vinci in San Francisco, Villa Kujoyama in Kyoto, and DAAD in Berlin. He has also written for his electric guitar orchestra, Sleaze Art. He then integrated computers into his work, via the programming language MAX.
His experimentation with computers continued, in 2003, with the creation of an instrument he calls the BassComputer, an electric bass with 5 fretted strings and 4 unfretted strings, as in the harp guitar. The instrument is intended to be interfaced with a computer. In 2004, he commissioned a piece from Eliane Radigue called Elemental II, which he interpreted for the BassComputer. This was an opportunity for him to set up his own label, ROSA (Recordings Of Sleaze Art). He later commissioned Phil Niblock’s Yam almost may (Touch Records TO59), and Dror Feiler’s Ousia. He also recorded Capture, one of his own compositions, on ROSA (Rosa#2, 2005), as well as ZKT, by Le Dépeupleur, a laptop duet, formed with Zbigniew Karkowski, and which has been together since 1999 (Rosa#3, 2006).
