Growing up in Hamburg, the seaport city where The Beatles once honed their craft through marathon sets at the Indra, Kaiserkeller and Star-Club, Rübcke’s childhood home was filled with books and records. His father, who worked for Philips Records, regularly brought home first pressings long before they entered general circulation. Black Sabbath, Jethro Tull and Nick Drake alongside shelves of jazz, progressive rock, beat music and R&B became the soundtrack of his childhood. At boarding school in southern Germany, he earned a reputation for arriving with homemade cassette compilations and introducing classmates to new discoveries, a habit he credits as “the beginning of getting stuck into music.”
Before music became his profession, Rübcke worked as a bookseller and waited tables by night while studying Japanese at university. His path later took him to Tokyo, where for six months he subsisted on bowls of miso soup. Back in Hamburg, his record collection grew rapidly around an early devotion to blues, R&B and funk, eventually leading to a Saturday night residency at the city’s celebrated Soul Kitchen. The brief was simple: “You could play everything, but it had to be between 1955 and 1976, nothing newer.” He still describes those years as “my grad school.” Around the same time came a split-second decision that would stay with him. Tired of being introduced as DJ Frank, he adopted the name Octupone, a riff on ‘octopole’, a physics term for an eightfold symmetrical field configuration.
