No saz or ney. Add spring reverb on piano, tape delay on vocals. At 0:25, a slow, hypnotic darbuka pattern enters with a warm, sub-heavy bassline. Maintain spaciousness throughout \u2014 wide stereo field, analog warmth. Avoid any electric guitar, fuzz, or desert blues elements. Build slowly, never exceeding a meditative energy. Vocals: ethereal, wordless textures and sparse phrases in a Nordic language (fictional or real). End with piano and sub bass fading into delay trails.",
