Diagonal welcome the return of Iranian composer and sound artist, Ata Ebtekar (SOTE), for his first outing for the label since 2019's "Parallel Persia" and "Artificial Neutrality". His catalogue runs to 15 albums (both under the Sote moniker and as Ata Ebtekar), plus a clutch of 12"s, remixes and a number of other projects via Mute, Opal Tapes, Warp and more.

"Soundsystem Persepolis" is Ata's response to the iconic performance at Persepolis by Iannis Xenakis in 1971. It's a five track collection of a futurism, a pummelling, rhythmic and harmonically complex trench of computer music.
