Untitled #274 was composed by Francisco López and performed by Kasper T. Toeplitz at GRM Studios in Paris, France. Francisco López is internationally recognized as one of the major figures of sound art and experimental music. For more than thirty years he has developed an astonishing sonic universe, absolutely personal and iconoclastic, based on a profound listening of the world. Destroying boundaries between industrial sounds and wilderness sound environments, shifting with passion from the limits of perception to the most dreadful abyss of sonic power, proposing a blind, profound, and transcendental listening, freed from the imperatives of knowledge and open to sensory and spiritual expansion. Kasper T. Toeplitz 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.
