Usher Raymond & Chris Brown

It's not often two artists with this many hits share the top of the same bill. Usher and Chris Brown bring their co-headlining R&B Tour to Gillette Stadium, packing one night with the songs that defined club playlists, house parties and road trips for more than two decades. Between them, the setlist is stacked with chart-toppers that still get an instant reaction the moment the opening notes hit. Seeing either artist in a stadium is an event. Seeing both on the same stage makes this one of the biggest R&B concerts to come through the Boston area all summer. If your group chat has ever argued over who has the stronger catalog, you'll probably keep that debate going all the way home.
