Birgit Ulher is amazing! Based in Hamburg since the early eighties, she has been involved in free improvisation and experimental music. She has established a distinguished grammar of sounds beyond the open trumpet. Plus working with radios and extended speakers, fed with radio noise in her trumpet mutes.

Czech experimental free improviser Petr Vrba seems like the perfect counterpart here with his unrelenting explorations of non-idiomatic music using trumpets, clarinets, electronics, vibrating speakers and more.

These recordings were made by Gunnar Lettow at Künstlerhaus Faktor in Hamburg, Germany in 2020.
