Wow, you haven't heard of the Foo Fighters or the Cardigans either? You're really out of the loop.
Again, my tastes have changed, I'm steadily going to heavier rock, I can easily see myself drifting to hard rock/punk music in the near future. But for the time being:
Guns N Roses
Jimi Hendrix
Led Zeppelin
Velvet Revolver
Slash's Snakepit
3 out of those 5 have Slash in them.
