After eleven years, a long-dormant signal reactivates from Hamburg’s hidden places: Helena Hauff and F#X return as Black Sites with R4 on Tresor Records—their first full-length album and the first release under the moniker since 2014. Like a hieroglyphic recently discovered and translated, R4 feels more like a long-awaited resumption than a comeback. To celebrate this release Büro Siebzig hosts a special live performance from F#X, followed by a Klubnacht curated by Black Sites.
