Welsh composer Karl Jenkins' wholly unique songs, masses, and requiems can be traced back through a legacy of wonderful pathbreaking music. Predecessors like Erik Satie, Miles Davis, and Maurice Ravel pointed toward his gripping melodic acumen and orchestrational brilliance, while the spiritual richness of music by Gabriel Fauré and J.S. Bach led the way for works like “Adiemus” and “Palladio.”
