"Thin Peaks" is the sixth album by the microtonal tuba trio Microtub, featuring Robin Hayward (UK/DE), Peder Simonsen (NO), and Martin Taxt (NO). Initially developed during an artist residency in Andersabo, Sweden, the two pieces "Thin Peaks" and "Andersabo” underwent several adaptations before being recorded in 2022. The pieces draw on the acoustic phenomena of half-valve combinations, creating distinctive timbres and harmonic spectra based on the unique half-valve signature of each tuba. Whilst "Thin Peaks" hockets between the pitches arising from a single half-valve combination, each of the four movements of "Andersabo" results from a different half-valve combination, sometimes resulting in surprisingly consonant harmonies.

Formed in 2010, Microtub have performed at prestigious festivals such as Sonic Acts in Amsterdam, MaerzMusik in Berlin, Wien Modern, FIMAV in Victoriaville, and Intonal in Malmö. Their music works particularly well in reverberant spaces. Some of the most memorable venues have been the Ex Teresa Cathedral in Mexico City, Brønshøy Water Tower in Copenhagen and Wasserspeicher in Berlin. Their latest performance in Sweden was at Lumen Projects in the Eric Ericson Hall in March 2024, where they also collaborated with Paris-based Egyptian singer Abdullah Miniawy. While Microtub primarily perform their own compositions, often in Just Intonation using the Hayward Tuning Vine software, they also frequently collaborate with composers such as Ellen Arkbro and Catherine Lamb. At the Ultima Festival in Oslo in September 2024, they will premiere seven new works by emerging composers from Norway, Poland, Iran, and the USA.

The band members are all very active in the experimental music scene worldwide. Hayward has collaborated with legends such as Eliane Radigue, Alvin Lucier and Christian Wolff, Taxt has performed with Verdensteateret, Tetuzi Akiyama and Toshimaru Nakumura, and Peder Simonsen has worked with Jo David Meyer Lysne and Bendik Giske.
