definetly look into:
them crooked vultures,
cage the elephant
..........these are all new bands. if you want some older bands here are some of my staples:
the pixies, nirvana, green day, the offspring,
the toadies, the clash
the killers, modest mouse, queens of the stone age
rolling stones, beatles
led zeppelin, cream
Judging by what you listen to, turn on your local rock radio station.
I made my suggestion based on what he likes!
