A raw, groove-driven selection of previously overlooked 1990s recordings by legendary Turkish jazz impresario Okay Temiz, compiled here for the first time. As the story goes, throughout the 1990s, Okay Temiz roamed the nights of İstanbul in search of rhythm — moving through its far corners, from the seedy underbelly to gypsy neighborhoods, from the outskirts of the city to smoke-filled taverns where cigarette haze turns into a living cloud atlas — capturing a largely unknown and maverick period of his work. Compiled by long-time producers Haluk Damar and Erinç Güzel, the album brings together Turkish folk textures, İstanbul tavern sound, spiritual jazz, raw street groove, and flashes of Turkish psychedelia — with moments shaped by Temiz’s own distinctive vocals. The result is a deep, percussive, and highly playable set. Positioned between global jazz, rare groove, and dancefloor material, İstanbul Groove is a strong crossover release with appeal across both listening and DJ set contexts.
