"Fairuz's 1978 album found her at somewhat of a crossroads in her career ... While the first side - exemplified here by the cascading drums, swooping strings, massed male chants and sublime Eastern scale-singing of Fairuz on "Baatilak" - provides a stellar exercise in the type of traditional fare that had long been her forte, the flip offers up a set of altogether more modernistic concoctions. Muscular basslines, funky guitars, punchy horns and Latin piano are melded with sublime strings and Fairuz's inimitable vocals on "Al Bostah" to refract disco through a Lebanese lens. The title track melds Fairuz's eastern melodies with jazz saxophones and lush, western-influenced, string arrangements to stunningly emotive effect. The singer would continue her East/West, Ziad Rahbani-assisted experiments on future albums, but Wahdon remains a shimmering benchmark".
