I just got the debut LP of a power trio of teenage sisters from Mexico, and it's quite possibly the most excited I've been about a musical debut in over a decade. It's called XXI Century Blood, and the band's name is The Warning, they did a
TedX talk a while back, and it put me on notice enough to watch out for what they ended up doing.
Here is the first single/video from it, which isn't the best song on it, but still quite good:

Other songs to check out are Survive, Wildfire and
Copper Bullets(the latter being more of a metal vibe, and probably their most polished overall composition), but the whole album is pretty damned impressive, especially when you consider their ages(13, 15 and 17). If they continue to mature in their songwriting(there's a bit of cliched teen girl angst in there, but not an offensive amount), they should be huge.
As it is, I have just been thrilled to see such raw enthusiasm and energy, and will definitely follow whatever they do next.
