The International Nothing is a Berlin-based psycho-acoustic clarinet duo formed by Michael Thieke and Kai Fagaschinski in 2000. They collectively compose multilayered sound sculptures using multiphonics, beat frequencies and difference tones as an integral part of their language. Both musicians are well known as improvisers but in this project they develop and perform exclusively their own compositions.

Every four years the duo releases an album on the Japanese Ftarri Label. In 2018 they are presenting their fourth duo album "In Doubt We Trust". While each of the previous releases consisted of several shorter pieces the duo is now going epic for the first time. The new album is made of a single work of 37 plus minutes. 2 1⁄2 years of deep sonic research in seclusion not only yielded a formal change, but also revealed new and yet unheard acoustic scenarios in slow pace and of fragile beauty.
