The iconic walls of Kastel echo once again — this time with the allure of darkness. The most enchanting and magical week of the year begins on Saturday, October 25, with Halloween Freakshow. Taking the spotlight is none other than Ferhat Albayrak, one of Turkey’s leading techno artists and the founder of Jeton Records. Blending Istanbul’s chaotic spirit with the dynamic and spiritual depth of techno, Ferhat Albayrak continues to make his mark on the global electronic music scene with performances spanning from Europe to America and Asia. Having played on prestigious stages such as Space Ibiza, Sonar Festival, Love Parade, and Rave The Planet Berlin, he invites the crowd at Kastel to a hypnotic sonic journey on this special night. This night is more than a celebration — it’s a ritual of mystery behind the masks, bodies dancing in the shadows, and a stage ruled by the extraordinary. With costumes, surprise performances, and a boundary-pushing stage design, music transforms into another universe at the heart of Istanbul. Among the names shaping the night’s atmosphere; GUN-HAN will raise the tension on the dance floor with his dark grooves and energetic flow, YMIR will add emotional depth to the night with his melodic touch, T-REVR will take over the stage with heavy basslines and industrial tones, while HTRONIC will conclude the night with his distinctive set blending different layers of electronic music. If your costume and ticket are ready — you’re invited to Kastel.
