Tiny Master of Today. They are amazing. So freaking good... and the amazing part, they are literally children. They're a brother sister duo from New York. At 13 and 11 they've been at this for a couple of years now. Check them out, you will LOVE them. I do.
They have a bunch of songs to listen to on their 'Space.
The other sweet band I just got into is Grand Ole Party... I love them cause their music sounds just like their name. Dig it.
