Jazz in The Gardens: Hans Koller - Rejoicing Ensemble feat. John O'Gallagher and Byron Wallen

Premiere of unique, exciting and explorative jazz orchestra project

Friday 25 April 2025

Jazz

Tickets: £15/25

Pianist and composer, Hans Koller premiers at World Heart Beat Embassy Gardens with a brand new jazz orchestra project featuring the utterly unique, explorative, and innovative improvisers John O’Gallagher (alto saxophone) and Byron Wallen (trumpet) as soloists. 

The new, original large-scale composition work debuting on the night is inspired by Koller’s ongoing fascination with symmetry and polyphony, George Russell’s Lydian-Chromatic Concept, O’Gallagher’s 12 tone improv, and the enduring folk music rootedness of jazz sensibility, rhythm, language, and community.

“Simply one of the UK’s most individual voices, both as a composer and pianist” Chris Parker

“Koller solves the perpetual jazz conundrum of making music for the mind and the body […] with an intelligence and vivacity that brings him ever closer to the stature of George Russell, Gil Evans, Mike Gibbs, and that long procession of his famous elders” John Fordham, The Guardian (Jazz Critic)

“Koller is an exuberant talent, his music full of surprises” Ian Carr, Rough Guide to Jazz (4th edition)
