The music written and improvised by Pierre Boespflug mixes the energy and surprises of jazz with the spectrum of colors of Olivier Messiaen's piano works. Focusing his research on the articulation between writing and improvisation, the formal and the sensitive, Pierre Boespflug proposes a world where the sound of the piano unfolds the infinite spectrum of its colors; not the color in the literal sense of the term but the one that provokes the imagination and leads us naturally to poetry. Couleur.S trio is the second part of a creation in the form of a tryptic (Couleur.S solo and Couleur.S sextet to come).
