Hans Koller was born into a musical family, his father was a jazz-loving Lutheran pastor, his mother a music teacher and his four sisters all played instruments.
Growing up in rural Bavaria, Koller first came into contact with jazz musicians in his teens while attending jazz summer schools run by Brian Abraham’s District Six in Ingolstadt. In 1991 he came to England, first to Middlesex University where he majored in composition, then at the School of Oriental and African Studies (SOAS) where he obtained a masters degree in Ethnomusicology.
Koller started playing in bands with saxophonist Stan Sulzmann and trumpeter Chris Batchelor and went on to form his own group, Neverland, with bass player Dave Whitford, saxophonist Rob Townsend and drummer Stuart Laurence. This group was augmented into a nine-piece outfit for Koller’s début album Magic Mountain (1997), which established him as one of the leading new jazz composers in the UK. Three years later he won the JOEY award for composers organised by Eastern Arts, and subsequently was awarded major commissions by Birmingham Jazz and by the Freden International Music Festival. In 2001 he released Lovers and Strangers, an album featuring his trio alongside the harpist Helen Tunstall, the singer Christine Tobin and the percussionist Corrina Sylvester.
His next album, New Memories (2002), was hailed as “the most expansive, expressive and exciting new jazz orchestral sound to have emerged in this country since the late-lamented Loose Tubes” by John Fordham in The Guardian.
“An exuberant and remarkable talent, Koller’s music is full of surprises.” – Ian Carr – Rough Guide to Jazz, 3rd edition / 2004
Over the next decade Koller worked on refining his sound, writing for Steve Lacy (London Ear), working in large group contexts with Evan Parker, and with Kenny Wheeler and Bob Brookmeyer, performing and recording with the NDR Bigband (Scenic Routes), as well as playing piano in various groups led by Mike Gibbs (including a tour of England in 2007 alongside Steve Swallow, Bill Frisell and Adam Nussbaum).
Subsequently, Koller produced a number of significant outputs of his own music including performances with Phil Woods and the BBC Big Band, a project with Dave Liebman, writing for the WDR Big Band with Gerard Presencer, a project with the HR Big Band, and, in 2009, an album with Bill Frisell and Evan Parker (Cry, Want). Koller had by then begun to focus on valve trombone, inspired by a 2006 study/stay at Bob Brookmeyer’s house, and started a fruitful small band partnership with drummer Jeff Williams, and bassist/trumpet player Percy Pursglove. He recorded quartet albums for Babel (Chasing the Unicorn), with Paris-based Canadian saxophonist François Théberge, for Evan Parker’s PSI label with the legendary German saxophonist Gerd Dudek (Day and Night), and in 2011 started forming a formidable creative partnership with NYC altoist John O’Gallagher. On their first meeting, Koller and O’Gallagher were memorably described by John Fordham in The Guardian as “two heavy weight theoreticians fizzing with jazz heat”, and the pair went on to work regularly, producing two BBC Radio 3 broadcasts, performances and recordings in both large ensemble and quartet contexts, and collaborating in a 2015 commission from Jazzlines to write for the renowned BCMG (Birmingham Contemporary Music Group).
Koller’s most ambitious work, his 2016 triple vinyl release Retrospection (on Stoney Lane Records) brought together over 30 of the world’s leading jazz musicians, including Steve Swallow, Jakob Bro, and the NDR Bigband.
Byron Wallen (b. 1969) was raised in a musical family and as a child studied classical piano, euphonium, trumpet, flute and drums. In the mid 1980’s the trumpet became Wallen’s primary instrument of choice. Wallen’s first major work, Tarot Suite, (1994) was inspired by a love of mythology and symbolism, which reflected the archetypal journey of human life through an interdisciplinary pan-continental approach. Wallen’s study of cognitive psychology has aided his transition towards conceptualising music as a medium for healing. Wallen raises awareness and invokes change by unlocking boundaries through the nature and science of sound. Widely recognised as a seminal figure in Jazz, Wallen is an acclaimed writer and producer whose original scores have been commissioned by The London Science Museum; PRS For Music, The BBC, Jerwood Foundation, Southbank Centre, National Theatre, Arts Council, FIFA and Sage Gateshead. He has also composed soundscapes for Universal Pictures, Warner Bros and Game of Thrones. Wallen’s current PRS commission ‘Anthem for Woolwich’ forges new links between schools, venues, musicians and residents to strengthen the resilience and promote the cohesion of the community. Wallen has received the BBC Jazz Innovation award (2003) and has been nominated several times for the MOBO award.
