A new kind of Hip Hop - Hollywood Undead

I have recently become addicted to listening to new and up and coming artists on myspace music. I have gone through a lot of music and I have to say my favourite music so far has come from an unknown group called Hollywood Undead who dont even have a album yet. They have described their music as Hip Hop / Hardcore / Screamo. I dont know what Genre that is but its pretty cool and makes a change from the normal Hip Hop you may always listen to. I think they are going to be huge as they are one of the most popular groups on myspace and their tracks have been listened to over 5 1/2 Million times. You can listen to them at myspace/hollywoodundead
