I wouldn't know any newer bands. We're past the pimple stage.
A lot of times you'll hear bands and it's a different sound coming out than what's on stage. Because you can clean it up through a PA and make it sound completely different than what they really sound like.
That's usually what happens with AC/DC: you make an album, and then you're on the road flat out. And the only time you ever get near a studio is generally after you've done a year of touring.
