Two flute solos simultaneously, one from the right, one from the left stereo channel - this is how the 48-minute track "Huchen 55", spread over LP sides 3 and 4, begins on Out Of Focus' third album "Four Letters Monday Afternoon" (1972, released on the Kuckuck label). As I said, 48 minutes and 1972. That's a minute longer and a year earlier than Mike Oldfield's "Tubular Bells"!
To avoid misunderstandings: Apart from the stringing together of various musical themes, "Huchen 55" has stylistically nothing in common with Oldfield's masterpiece. Out Of Focus were Anglo-American influenced. The band allowed for slight psychedelic influences, but also relied primarily on jazzy, progressive elements and a jam character that was evident in the sprawling solos on guitar, organ, flute and saxophone.
