XKatedral is a record label focused on presenting music by composers primarily working with slowly evolving harmonic and timbral music achieved by electronic and acoustic means.

Founded in 2015 by artists Kali Malone and Maria W Horn, XKatedral began as a small tape label and concert series focused on contemporary minimalism and drone music by themselves and their peers. The early releases of works by Horn, Malone and Ellen Arkbro, Caterina Barbieri, Mats Erlandsson and David Granström among others, quickly gained an international cult following, leading the label to grow into a broader production platform.

Today XKatedral is co-managed by Mats Erlandsson, Daniel M Karlsson, Theodor Kentros, Sara Fors, and Stephen O'Malley, who collaborate on recording sessions, mixing and mastering, and bespoke artwork for the label's releases and events.

Now entering it's second decade in existence, XKatedral stays committed to it's mission of presenting spectral monoliths and subtle figurations slowly moving through the realm of tuning, timbre and time.
