There he met the immensely popular Nubian singer Mohamed Mounir. They began a collaboration that was to influence the course of Egyptian pop music, lending a note of sophistication and international influence to the genre. One of the many highlights of Bunka´s work with Mounir as arranger and oud soloist, was their appearance in the 1992 Mediterranean Culture Festival in Nimes France, as Egypt´s representatives.

With solo-concerts in Tunis (Festival de la Medina), Cairo, Damascus, Aleppo and Beirut as well as in Lanzarote with the group Vox (CD: Spain to Spain, Erdenklang Rec.); and his performance at the Jazz Festival in Granada, Bunka, according to P. Pannke, brought his "very personal journey to explore the world of Arabic music" closer to a growing world-music audience.

Bunka´s credits as studio musician include work with one of Algeria´s best known singers Hamid Baroudi and the German Ethno-pop group Dissidenten. He also performed with Nagaswaran-player Roland Schaeffer and masterdrummer Paramashivam Pilai, The Karnataka College of Percussion, Charlie Mariano and Edgar Hofmann.

Roman Bunka composed the score and provided musical direction for the feature film "Al Oud" (Director: Fritz Baumann) that won the Gold Hugo at the 1992 Chicago International Film Festival. While shooting, he became involved with the violin virtuoso Abdo Dagir from Cairo, and was largely responsible for introducing the works of this master composer and musician to the Western world. (CD "Malik-a-Taksim" ENJA Rec.) He studied under Abdo Dagir and toured with his ensemble throughout Europe and Egypt.
