Thanks for this! The sound owes a debt to Barış Manço (1943-1999), pioneer of Anatolian rock. His folk psychedelic "Dere Boyu Kavaklar" (1975) includes Oktay Aldoğan playing a soprano and a tenor sax in harmony. The ballad "Gülpembe" (1981) combines flute and heavy guitar, though not quite the Norman Greenbaum territory of Umut Adan. Manço's career spanned a wide range of styles, including many children's favorites and the weird concept album 2023. His sudden death by heart attack left Turkey in shock, as the retrospective double-album Mançoloji was released with the instrumental "40. Yıl" celebrating 40 years making music. Remembering Barış Manço: Turkey’s music legend The car in the video you posted is an Anadol A1 (1966–1975), Turkey's first mass-production car, designed by Ogle, source of the Raleigh Chopper, Triumph Trident, XP-34 Landspeeder, and the infamous Reliant Robin.
The car, minus rooftop stereo, was featured on Bring a Trailer in 2018.
