I think AC/DC would be perfect, they are the last of the great “arena rock” bands.
The WHO also performed at the Concert for NY after 911. I will be forever grateful for their participation. In fact, they stole the show that night.
I think Guns and Roses would have been even better....not as “aged” as ACDC.....
Journey or Toto would be good too. Even my college age daughter likes them a lot.
