Ever since the early 1990s Atanasios 'Ata' Christos Macias has been an integral figure of Frankfurt's electronic music scene: As a founder of Delirium (together with Heiko M/S/O and Jörg Henze), the Playhouse and Klang Elektronik labels (with Heiko and the boys from Alter Ego), and as a DJ at Omen, Dorian Gray and XS he's had a hand in many of the city's techno institutions. In 1998 he set out to found another one: Offenbach's Robert Johnson club, which he runs to this day together with partner Sebastian Kahrs.
