I'd recommend The Wildhearts-A fantastic pop/rock/punk band from England.They've been about for years but their new album The Wildhearts Must Be Destroyed is a classic.
Check them out at

Everyone is hyping The Darkness but Wildhearts album is much better.
Also check out The Donnas an American all girl rock band at

You can listen to most of the album on the site.
