I thought it was a great Super Bowl, even without my favorite team in it. And I'm glad the Patriots didn't win another one.
I was thinking about the halftime show. It was pretty good and JT is a great artist. Then I was thinking about the last time a rock band headlined the half time show. You have to go back to 2010 with The Who.
Then I wondered, who would be the next real rock band to headline the Super Bowl halftime show? Is there anyone that's big right now that could do a halftime show?
I guess they could bring an older band out for a greatest hits show. I just can't think of any current actual ROCK band that could pull it off.
As you mentioned, Foo Fighters could do it for sure. They could even collaborate with other artists if there was concern over "mainstream appeal" or whatever.
Metallica also comes to mind as a huge name that still tours frequently. However, their music doesn't appeal to all.
