When I first heard them at Lollapalooza via their livestream on Youtube I was blown away. Such a unique sound the wail of the guitar and the echoing of their sound was a lot for me to register at once. This was a sound i've not heard before yet it made me feel like i've known it my whole life in the very moments of hearing them. They are one of a few groups I saw on this livestream that are worth mentioning here to bring to the Rock Band network. I'll post a link to one of their songs below.
