If you could...?

Maybe I would play guitar along with John Petrucci in Dream Theater. This band is awesome.

I would choose Dream Theater (if I had the massive instrumental ability that they have), and I would pick the instrument of keyboards. I don't think that Jordan Rudess is too much beyond a excellent keyboard player; he doesn't add to the band creatively. His playing is generally just to show off. It is very rare for him to play something tasteful when he plays a lead.

I'd love to play guitar on Iron Maiden, but they are already like 3 guitar players, so I can't imagine what it would be like! LOL! :)

I'd play rhythm guitar in Metallica, bit hard to match up with Hetfield though lol.
