Weezer turns Toyota Center into a loud, colorful alt-rock reunion with The Shins and Silversun Pickups joining the bill. The Gathering pairs giant guitar hooks and wonderfully awkward anthems with two bands that helped shape different corners of indie rock. Expect a room full of fans shouting every word to familiar favorites, then leaning into fuzzy new material and deeper cuts. Arrive for the openers; this is a rare three-band arena bill where every set matters.
