***Sublime Frequencies finally unleashes its essential compilation from 1970s Egypt, produced and compiled by Hisham Mayet . Modal instrumental tracks from Baligh Hamdi -- one of the most important Arabic composers of the 20th Century (writing for legends Umm Kalthum , Abdel Halim Hafez , Sabah , Warda , and many others). Features his legendary group the Diamond Orchestra with Omar Khorshid on guitar, Magdi al-Husseini on organ, Samir Sourour on saxophone, and Faruq Salama on accordion. All of these musicians were discovered and recruited by Hamdi to interpret his vision of a modernized, hybrid Arabic music. Under Hamdi's direction, this orchestra charted a new melodic direction and created a new musical language. This compilation is culled from a specific era of Hamdi's long career, a decade where he fully realized an international music which incorporated beat driven Eastern-tinged jazz, theremin draped orchestral noir, tracks that feature searing guitar solos from none other than Omar Khorshid, and a selection of buzzing, sitar driven, Indo-Arabic tracks establishing a meeting of mid-east and eastern psychedelic exotica, and a vision that created some of the hippest music coming out of the Middle East from the late 1960s and throughout the 1970s. Includes extensive liner notes by Hisham Mayet with rare photographs. Housed in tip-on gatefold jackets.
