Orhan Gencebay makes music in an Arabesque style. I don't know how many items he made with "progressive" touches in the instrumentation. I believe within the range of the genre of the Arabesque music he opened this up with some fusions and crossovers from within.
There must be various singles (starting from at least 1967) outstanding for this. Also the LP "Leyla Ile Mecna" (1983) is a nice examples of crossover Arabesque music coloured with electric baglama, electric guitars, harmonica, electronic music instrumrents,... a very nice and highly recommended album ! :
"Orhan Gencebay plays stringed instruments originating from Turkish culture called "Baglama" in Turkish , as well the Electric Baglama besides Sitar (and even Tenor Saxophone). Within these experiences in his approach to Turkish music he produced natural sounds with instruments that were played this way before. Neutral critics and himself always impressed on one subject "to sound like Pink Floyd". Orhan Gencebay succeeded completely to blend orient and eastern tunes into one shape in new way he had started. His "progressive" music was understood as being arabesque amongst people except for some as a result his music was prohibited and sometimes limited in Turkey (on TVs, Radios etc). As words can be his music was a protest as well. Erkin Koray covered his songs like "Hor Gorme Garibi", "Goca Dunya". Erkin and Orhan were and still are good friends and worked together for a time where their minds influenced each other (see picture on top left) . Finally I can say that Orhan is very rare musician in the world that performed progressive tunes with a naturel instrument (in a way it can be seen how some indian musicians performed with their sitar also). Therefore he also used the Electric or Electro Baglama. (somewhat like a Guitar with magnetics and circuits as well). His music can be called Ethno or World (Fusion) because he used scales from Blues, Rock, Funk etc. He is performing this type of music for over 30 years for reason of art only, not for the reasons like nowadays some musicians blends some Indian, Mid-eastern melodies and call it "World Music" or "Ethnic" just for money. He was one of the real starters of that type." Ozan Durmus
I don't know which other albums have this crosover attitude.
In the movie "Crossing the Bridge" the interviewer asked Orhan about this "Arabesk style", which he said came from people who listened to Arab flavoured music on the radio. But, he said, the Arabesk singing and arrangement style origin in Turkey more lays in countries like for instance Egypt.
Other ok audio files to give an idea of the general O.G. style (no highlighting moments) :
