Foster The People. Lots of people are comparing them to Phoenix, Peter Bjorn and John and MGMT. They have a great sound and catchy chorus. I would not be terribly surprised if this Indie band crosses over to mainstream radio.
Hugo. This guy made a sweet remake of 99 Problems by Jay Z. He also has a good song called "Bread and Butter". He will be performing at SXSW this year. Check him out.Tinie Tempah. This guy is huge in the UK. His Trans-Atlantic emergence is inevitable. If you ask me, he sounds a bit like Taio Cruz with the New Zealand guys from Flight of the Concords on HBO doing their comedic rap "Hiphopopotamus vs. Rhymenoceros" You'll see what I mean.
Beady Eyes. This band is new but not really. They are the majority of Oasis without Noel. If you like Oasis, you will like this disc. It is a bit more toned down than Oasis, but a great listen.
