I listened to Queen when I was 15, but that was almost 10 years ago. I would be in for a Queen or a David Bowie pin!
If you want to do a new band, and still cater to the Australians, do Tame Impala. They've got a classic sound and a wide variety of songs just on their first 2 albums. They were on NPR, and they're doing their first US tour (Extremely unlikely, I wouldn't expect this to ever happen).
The Flaming Lips would be a band that spans generations. Oklahoma changed their state song to "Do You Realize" about a year or so ago. Flaming Lips would be weird enough to make a pinball machine after. I would see a Twilight Zone-esque machine, with a bunch of stuff going on (Very unlikely, but technically probably more likely than Tame Impala).
Now another newer band that I would actually want to see? Broken Social Scene or Dinosaur Jr... I don't know why I even type this stuff out! I just get my own hopes up!
In summary, if they haven't had a screen printed t-shirt in Target or Wal-Mart, they're not going to have a pinball machine.
