"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.

She has been organising the festival of improvised music Real Time Music Meeting for over ten years.

"Leonel Kaplan (Buenos Aires, 1973) plays the cornet. He has been part of the international experimental music and free improvisation scene since the early 2000s, working between free jazz, European reductionism, and the post-Onkyo currents.

Paul Serralheiro, writing in Squid's Ear, placed his work outside the era of Miles - the trumpet (and now the cornet) treated as a resonating body, a drone device, a breath zone before a tone. Dan Warburton, in Paris Transatlantic, called it "relaxed intensity". The descriptions stuck.

He has recorded with Axel Dörner and Diego Chamy (Absence, Creative Sources, 2005), Audrey Chen and Nate Wooley (Silo, Utech, 2006), Tetuzi Akiyama and Edén Carrasco (Moments of Falling Petals, Dromos, 2009), Christof Kurzmann (Una Casa / Observatorio, Casa Corp, Pandemic Conversations), John Butcher (Shortening Distance, L'innomable, 2013), Klaus Filip (Tocando Fondo, Another Timbre, 2015), and on his own (Trumpet, Another Timbre). Live and on record he has worked with Michel Doneda, Lê Quan Ninh, Tatsuya Nakatani, Greg Kelley, Franz Hautzinger, Ivar Grydeland, and Wade Matthews, among many others.

From the early 2000s through 2024 he kept a parallel practice composing for theatre, dance, and light installations - Hotel der Immigranten with Anna-Sophie Mahler (Kaserne Basel, Gessnerallee Zürich, Hellerau Dresden), Orlando with Julie Beauvais and Christophe Fellay (FIBA Buenos Aires), and pieces with Nicole Bindler and Ly Thanh Thien. The longest thread was with light artist Aleksandra Stratimirović: Underworld, Brilliance - Inside the Sun, Great Minds, Color Wheels, Waves, shown across Sweden, Finland, Norway, Austria, Slovenia, Italy, North Macedonia, Bosnia, Singapore, and Brazil.

He has lived in Belgrade since 2018. He plays regularly at KC Grad, UK Parobrod, Club Ciglana, Ring Ring Festival, and the Belgrade Festival of Light, in formations with Marina Džukljev, Milana Zarić, Branislav Radojković, Ilia Belorukov, María Valencia, and Franz Hautzinger, and brings longtime interlocutors - Filip, Kurzmann, Hautzinger - through the city."
