[PLACEHOLDER — update once NBC confirms lineup, likely 12ish hours before air] America’s Got Talent Season 21 returns tonight, Tuesday, September 1 at 8/7c on NBC, for Quarterfinals 3. Eleven more acts from the Top 44 take the stage, with America’s vote sending three through to the Semifinals — plus one more act getting sent straight to the Finale via this week’s Golden Buzzer.

How Quarterfinals 3 Works

The Top 44 acts were split into four groups of 11, each performing across a separate week of the Live Quarterfinals. On performance night, the judges give their feedback, but it’s viewers who decide who moves on — America’s vote sends three acts per week to the Semifinals, while a Golden Buzzer (judge or host) can send one act directly to the Finale.

Two acts are already locked into the Finale from earlier rounds: magician Hundred Fingers (Howie Mandel’s Golden Buzzer, Quarterfinals 1) and rock vocalist Nene Royal (Mel B’s Golden Buzzer, Quarterfinals 2, for her cover of “Black Hole Sun”).
