Karl Jenkins is a Welsh composer and musician from Penclawdd, Gower, who began his professional career in the late 1960s as a jazz and jazz‑rock performer and session musician. He later transitioned into composing orchestral, choral and classical‑crossover works that blend classical instrumentation with world‑music rhythms, invented vocalise and electronic textures, with the Adiemus project exemplifying his fusion of modal melodies, layered percussion and accessible choral writing often used in concert programming and media.
