Arab pop A-lister Nancy Ajram possesses skill and magnetism that transform with each song. Alternating between dramatic orchestrations, fiery, hip-shaking percussion, melodic keys and electronic beats—these classic voices and pop peers have fuelled her widely successful output: Salwa El Katrib's theatricality, Sabah's passion and vitality, and Moustafa Amar's synth-laden rhythms, to name a few.
