Most, but Potentially All is a groundbreaking electroacoustic composition by Norwegian trumpeter Eivind Lønning, entirely composed, recorded, mixed, and mastered by Jim O’Rourke. The album features Lønning's virtuosic trumpet performances, which O’Rourke processes through his Kyma system, resulting in a captivating blend of acoustic and electronic textures. The piece unfolds in three parts, each exploring different sonic landscapes, from subtle, bird-like horn wails to dense, hallucinatory drones and minimalistic, reverb-laden passages. The collaboration showcases a deep interplay between Lønning's improvisation and O’Rourke's meticulous electronic manipulation, setting a new standard in contemporary experimental music.
