The Troys!
Watch ‘What Do I Do’ here
They are 2 teenage sisters, Anna and Lindsey and their band of 3 guys. They have nice clothes and a fab video, so I was a little disappointed that the song is a bit Hilary Duff-ish, especially when they cited the ace No Doubt and Garbage as their influences. Still it’s very catchy and hopefully their other material is a bit more original.
