Since the 1970s Mario De Leo works as a musician and visual artist. His mechanical paintings are hybrid works that reveal the cosmic spiritualism hidden in the meanders of electronics. With Riccardo Sinigaglia (Futuro Antico, Correnti Magnetiche, Doubling Riders) De Leo consolidates an artistic and human partnership with Lettera Cosmica, a work unpublished to date, produced and recorded in 1981. In a wacky electronic vision of the succession of time, the tracks trace the four seasons in a fine process of analog loops, prepared tapes of strings and piano, time and pitch shifts, filtering with Synthi Ems and Teac 3340 4-track recorder. On this seemingly cold palette, De Leo deploys his own personal Mediterranean fingerpicking, with vocal timbres peculiar to the music of the South of Italy, but no longer circumscribed to the origins of his Pugliese regionalism, as much as to an expressive range seasoned also with irony and avant-garde.The sound writing harmonizes with the evocative cover, in which emerges a warmest human note of “technological peasant”.
