The Canadian singer-songwriter Nemah Hasan, a.k.a. Nemahsis, is back with two singles in advance of her debut album that will be coming out later this year. She tells Tom why she sat in a car wash with total strangers and asked them to listen to her song “You Wore it Better,” what happened when her label dropped her last fall, and what it was like shooting a music video for her song “Stick of Gum” in her family’s home of Jericho in the West Bank.
