“The Great Divide Tour” arrives at Citi Field as a stadium-scale rock/pop bill anchored by Noah Kahan, with featured sets from Gigi Perez and Annabelle Dinda. Framed as a live concert event in Queens, it places contemporary songwriting in a space more often associated with New York’s summer sports calendar. If this tour marks a first New York City appearance for any of the performers, it reads as a measuring point in their ascent. The lineup’s shared emphasis on narrative lyrics gives the night a coherent throughline.
