Sole album from an early 70's German (from Hamburg I think) sextet Ikarus, whose reputation as a pioneer of jazz-rock is a bit over-done. Let's just say that they're a typical prog group with symphonic and jazz influences, a bit ala Crimson. Lead by multi-instrumentalist Jochen Petersen (guitars & winds), the group develops a wide soundscape in just four tracks (the shortest being well over 6 mins) that goes as far as electronic twiddling and string arrangements.
Essential: a masterpiece of progressive rock music.
IKARUS were an early 6 piece Krautrock band who sang in English and featured sax, flute, clarinet, organ, piano and some strings besides the usual instruments.
