Isabel Dumaa may not have been the most familiar name on this year’s Summerfest lineup, but by the time her set wrapped on Friday, it was clear Milwaukee had just witnessed one of the best breakout acts of the festival. Performing a late-afternoon set on the Briggs & Stratton Big Backyard stage, Dumaa brought the kind of warmth, charm, and raw talent that instantly made fans out of first-time listeners.

Armed with a guitar and a voice that blends vulnerability with polish, the California-born singer-songwriter shared originals from her debut project Just My Nature, captivating the crowd with standout tracks like “Quarter Life Crisis” and “C’est La Vie.” Her indie-pop melodies, poetic lyrics, and stage presence made her performance feel both intimate and full of potential, the kind of set that leaves you saying, “Wait, who was that?” before quickly adding her to your playlist.

Isabel Dumaa didn’t need pyro or flashy visuals to win over the Summerfest crowd, just great songs, a clear sense of self, and the quiet power of an artist at the very beginning of something special. Keep an eye on her, we definitely will.
