Led by double bassist and composer Thomas Julienne, Theorem of joy‘s third opus represents the most accomplished statement from this Parisian quintet, whose innovative fusion of poetry and jazz incorporates North African melodies, post-rock adventures, and Eastern harmonic influences into a distinctly contemporary European sound.

The album’s thematic focus on fire as a symbol of transformation, destruction, and renewal permeates compositions like ‘New Spring’, which Julienne describes as representing fresh beginnings, “the first breath—wild, radiant, and full of promise”. The inclusion of vocalist Raphaëlle Brochet adds another textural dimension, particularly on tracks like ‘Au Monde’ and ‘Little Raymonde’, where her vocals interweave with Robin Antunes’s processed violin to create atmospheric soundscapes that blur the boundaries between jazz and chamber music.

Julienne’s compositions reveal him as a keen observer of contemporary psychological and sociological dynamics, with tracks like ‘Behind the Sky’ and ‘Ideal Robots’ exploring themes of environmental consciousness and technological alienation. The rhythm section of drummer Tom Peyron provides the perfect foundation for Anthony Winzenrieth’s guitar explorations, while guest appearances by cellist Sary Khalife and trombonist Robinson Khoury expand the ensemble’s timbral palette. The album’s flow from the opening ‘New Spring’ through the closing ‘Ideal Robots creates a compelling narrative arc that confirms Theorem of joy’s position at the forefront of 21st-century French jazz innovation.
