Bruno Mars hit the pop music scene hard a couple years ago with his debut album, "Doo-Wops & Hooligans". He announced his presence with the single "Grenade", and even got to perform at the Grammy's. Now he's out with his second album, "Unorthodox Jukebox", and keeping his fresh sound out there.

Also this week, we have the third installment of Green Day's triple album. After "Uno" and "Dos", what else, it's "Tre". The powerful, pop-punk trio has been at it for twenty years now. There's no word yet on a possible summer tour.
