A raw and elemental solo tenor saxophone album from Malaysian improviser Yong Yandsen, Mud plunges into the dense, textural world he has explored in his group recordings with Sabu Toyozumi, Rick Countryman, Christian Meaas Svendsen, Paal Nilssen-Love, and others. Known for channeling influences like Kaoru Abe, Albert Ayler, and John Butcher into a personal, highly physical language, Yandsen pushes even further here, drawing out wet, grainy, and murky timbres that justify the album's title.

Across the program he works with extreme embouchure strain, unstable multiphonics, swallowed subtones, and breath-laden noise, shaping them into long arcs that feel as though the horn is dredging sound from beneath the surface. Rather than showcasing virtuosity in a conventional sense, Mud immerses the listener in a shifting acoustic terrain where pitch, pressure, and texture smear into each other-an absorbing document of Yandsen's uncompromising solo voice and a notable addition to the Deathrash Armaggedon catalog.
