With studio releases stretching back to the 1990s, Assala, aka Assala Nasri, has decades-worth of pan-Arabic hits to choose from—and she packs 18 of them into a special, nearly two-hour performance on Assala Night. In typical fashion, the remarkable vocalist casts her spell from the get-go with the romantic gem “Qad El Horoof” awash with strings and interspersed with enthusiastic applause; it is followed by a harp-enhanced “Thak El Ghaby” that fans heartily sing before the artist herself approaches the mic, setting the tone early on for a celebration of enduring live mastery and unexpected emotion.
