All compositions by Christian Wallumrod. Trondheim Voices is a groundbreaking Norwegian ensemble of improvising vocalists, constantly challenging and changing the framework for how a vocal ensemble can produce sound art. Each singer's individuality, and her timbre combined with the other voices, are in focus, resulting in a unique quality to the groups collective sound. Through their many collaborations with cutting edge composers like Christian Wallumrod, Marilyn Mazur, Jon Balke, Mats Gustavsson and Maja Ratkje, they have made solid statements as developers within vocal and improvised music. Trondheim Voices are exploring and developing new music in the interaction between the singers, the audience, their surroundings and new technology. Christian Wallumrod has worked as a musician and composer since 1992, and he is considered one of the most prominent and influential musicians of his generation in Norway. Following his debut on ECM Records ("No Birch", 1996), he has released a string of albums with Christian Wallumrod Ensemble (CWE) on the same label, all to considerable critical acclaim. The album "Outstairs" (2013) was awarded the Norwegian Grammy's (Spellemannprisen). Brutter (2012), Christian's collaboration with drummer brother Fredrik, has released three albums (Hubro). Hubro is also the home for albums with CWE and Dans Les Arbres, as well as Wallumrod's solo piano records Pianokammer (2015) and Speaksome (2021). Wallumrod has written commissioned works for Ensemble Allegria, Håkon Stene, Oslo Strykekvartett, BOA and Trondheim Jazz Orchestra.
