An excellent, yet very obscure, mid-70's Italian progressive, taking a step on from the likes of: PFM, LDF, or Il Volo, with a very symphonic classically. Errata Corrige uses multi-guitars, piano, cello, synthesizers, bass, flute and drums. They develop a very complex (dramatic and dreamy) style, blending spacious symphonics with a poetic Italian lyrics. Their superb, gentle vocal harmonies (in Italian) are complimentary to the music. "Siegfried, Il Drago e Altre Storie (1976)" is the excellent debut album, and after a long gap, this was foolowed by "Mappamundo (1991)" .
