Al MacSween continues to emerge as one of the most creative voices in London's contemporary jazz scene with Where Rivers Meet, a remarkable collaboration between his collective Your Brother's Keeper and legendary saxophonist Gary Bartz. As pianist, synthesist, composer, and producer, MacSween creates a rich sonic landscape that blends acoustic jazz with modular synthesis and live electronics, allowing Bartz's iconic saxophone to interact with modern textures while preserving its emotional depth. Originally developing through collaborations in Maisha, the project reflects years of shared performance and musical trust. McSween's vision places collective improvisation at the center, bringing together trumpeter Axel Kaner-Lidstrom, bassist Twm Dylan, percussionist Tim Doyle, and saxophonist Chelsea Carmichael. Rather than simply accompanying a jazz legend, Your Brother's Keeper engages Bartz in a genuine artistic dialogue, demonstrating MacSween's gift for connecting generations while pushing the boundaries of spiritual and contemporary jazz.
