As with many a project that’s been in development for over a decade, especially a new musical from new writers, you can sense the Lazours’ mad rush to get everything they want onto the page initially, as well as the toothiness that sets in after too many rounds of workshops and revisions (We Live in Cairo was at ART back in 2019 and has moved through a bevy of other developmental programs). Their book, in the first act, strains as it gets these characters on their feet while also offering the audience a primer on 2010s Egyptian politics; often, they default to rote exposition, which Magar has the actors deliver dutifully. We’re told the differences between the characters’ backgrounds and political stances — the two brothers are Coptic Christians, the others are generally secular Muslims, and Karim befriends an acolyte, Hassan (Drew Elhamalawy), whose family members are Muslim Brotherhood — in bursts of dialogue where you might hope for the tension to lie in action or music. The songs, some of which made it onto an album released during the pandemic, contain real highs, like an a cappella number that introduces the second act, though there are also darlings that express a feeling well but don’t service the drama in situ.
