Birgit Ulher: trumpet, radio, speakers, objects
Born 1961 in Nuremberg, she studied the visual arts, which still have an important influence on her music. Since moving to Hamburg in 1982 she has been involved in free improvisation and experimental music. Since then she has “established a distinguished grammar of sounds beyond the open trumpet” (jazzdimensions.de). She works mainly on extending the sounding possiblities of the trumpet by using splitting sounds, multiphonics and granular sounds and has developed her own extended techniques and preparations for producing these sounds. Besides this material research she is especially interested in the relation between sound and silence. Since 2006 Birgit Ulher works with radios and uses extended speakers, fed with radio noise in her trumpet mutes. The trumpet functions as an acoustic chamber and modulates the radio noise, thus the trumpet is transmitter and receiver at the same time. Her work with radio is documented on the CD 'Radio Silence No More', released 2007 on Olof Bright. The same concept is the basis of the duo with Gregory Büttner, where Büttner plays his sound contributions via a laptop with an output to a small speaker which Ulher uses a s trumpet mute.Their first CD 'Tehricks' based on this concept was released 2009. She performs solo, with dancers, working ensembles, and one-time collaborations with musicians from around the world.

Ute Wassermann: voice, birdcalls
Ute is known as a vocal soloist and composer/performer and for her extraordinary, many-voiced and extreme vocal sound-language, which she has brought into experimental/contemporary sound in diverse ways. She is engaged in the area between composition and improvisation, sound and performance art as well as in free improvisation. She studied visual arts (sound installation, performance art) at the Academy of Fine Arts in Hamburg, and subsequently visual art and singing at the University of California, San Diego. Ute´s singing seems to be disconnected from the voice creating a soundworld of birds, machines, electronics. She masks her voice using bird whistles, palate whistles, speaker objects, resonators. Numerous performances as a vocal soloist in festivals, galleries and clubs throughout Europe, Australia and Asia. Premieres of numerous works by composers especially written for her voice. Performances with different bands and adhoc with sound-artists like Birgit Ulher, Phil Minton, Thomas Lehn, Martin Blume, John Russel, Raed Yassin, Michael Vorfeld, Les Femmes Savantes. Recent commissions for compositions by Ryogoku Art Festival, University of Amsterdam and Poetica Sonora, Mexico City. She has received several grants like a residency at the Civitella Ranieri Foundation in 2015.

Tom Arthurs: trumpet
Tom is a true sound artist for the 21st century, drawing honestly and effortlessly from a dizzying range of influences. His sonic represents a rare beauty and creative depth, and he cites inspiration from the likes of John Taylor, Kenny Wheeler and Jimmy Guiffre, Berlin’s Echtzeitmusik scene, György Ligeti, Luc Ferrari, Wolfgang Mitterer and Morton Feldman, Andrei Tarkovsky and Jean-Luc Godard, Lau Tzu and Farid Ud-Din Attar, as well as baroque music, the pygmies of Central Africa, Gal Costa, David Sylvian and Arto Lindsay. Already by his mid-30s, news of Arthurs’ finesse, glowing sound and relentless creativity has spread far and wide, with New York City Jazz Record’s Thomas Conrad describing his playing as ”continuously, beautifully unfamiliar”, and allaboutjazz’s John Kelman describing his improvisations as “simple but perfect”, demonstrating “an exacting perfection” and with “a harmon-muted tone that renders his playing as vulnerable as Miles Davis at his fragile best”. Closer to home, Tom has been described as “a world-class improviser” by UK’s Jazzwise, “une révélation” by France’s Citizenjazz, and ‘der Glasbläser’ (the glass-blower) by Germany’s SWR2.

His current projects as leader are two international trios: the first with British pianist Richard Fairhurst and Finnish drummer Markku Ounaskari, and the second with French bassist Sébastien Boisseau and Swedish drummer Jon Fält. Tom is at equally home with a range of collective improvised projects (including GLUE, QUAIRÓS and Pedesis), and he has been awarded composition commissions from the BBC/RPS, City of London Festival, BBC Proms, the Elias Quartet and the BBC Concert Orchestra. He has worked with folk musicians including The Unthanks and James Yorkston, and once contributed a significant sonic cameo to legendary BBC TV series The Mighty Boosh. Tom has performed and recorded with Ingrid Laubrock, Dine Doneff (Kostas Theodorou), Denis Badault, Julia Hülsmann and Theo Bleckmann, and has shared the stage with an incredible range of artists, including John Surman, John Taylor, Kenny Wheeler, Benoît Delbecq, Jack DeJohnette, Régis Huby, Joanna MacGregor, Iain Ballamy, Thomas Strønen, Ignaz Schick, Jan Bang, Nicolas Masson, Julie Sassoon, Tom Rainey, Drew Gress, Rudi Mahall, Eddie Prévost, Willi Kellers and Steve Beresford. Arthurs also plays regularly with the very finest of his own generation – including Marc Schmolling, Almut Kühne, Miles Perkin, Maciej Obara, Philipp Gropper, Ronny Graupe and Wanja Slavin.
