For six decades, singer and oud player Mohammad Abdu has been synonymous with Saudi music, gaining legendary status for his virtuosic performances of national songs—of which he has sung hundreds—home-grown folk and original compositions. On the first night of this live celebration of his Diamond Jubilee, emotive flurries of strings usher in an epic “Sout Yenadeni” before a captivated audience. Francophone pop star Lara Fabian later joins him for a heart-rending medley of “Je suis malade” and “Magmoua Ensan”—encapsulating, in a matter of minutes, Abdu’s emotional gravitas, versatility and far-flung reach.
