Bleep

The majority of Russell Haswell and Florian Hecker’s collaborations have involved the UPIC system developed by Iannis Xenakis to render sound from images, so there couldn’t be a better time for their return than with a composition made for Xenakis’s 100th birthday. UPIC Diffusion Session #23 is their first release in over a decade, with endless voicings of synths that zip and slide through frequencies. Each sound spins and gushes with articulation, sputtering in and out of life, with warped and twitching harmonies that feel as if you’re listening to raw data itself.
