Alex Tsiridis, half of Cassegrain launched the Rhyw alias in 2016 with an EP on Rotterdam's Tar Hallow. (by Luke Cheadle, XLR8R) . His second release under this name is the five-track Cave Walls (Part One), the fifth release on Shifted's label Avian in 2017.

In techno circles, Cassegrain shouldn't need too much of an introduction. With a label résumé that includes, among others, Prologue, Infrastructure New York, Killekill, and Ostgut Ton — as well as highly regarded performances at Berghain, Village Underground, and Output — they've more than stamped their name on the scene.

Alex Tsiridis and Hüseyin Evirgen — the two artists behind Cassegrain — formed the project after a chance meeting at the Redbull Music Academy in Barcelona. In the years following, they collaborated remotely via email, sending stems back and forth before making a move to Berlin where they currently share a studio.
