A pair of my friends went to V Fest here in Toronto, Wintersleep performed, and for about three months, all I heard was "Oh my god, wintersleep is SO AWESOME!" from like all of my indie oriented friends. Initially I resisted liking them, probably to stick out from the crowd. But eventually I caved, and I strongly enjoy a few of their songs now. They are supposed to be immense live. (Not actually physically immensely, but you probably get the idea.) I haven't listened to the new album.
On a side note, I was going up to Muskoka (for those of you that don't know, its a really nice cottaging area around Lake Huron/Georgian Bay in Ontario), and it was really misty and foggy and rainy, and Wintersleep was perfect. The first two albums really give off a "great wild north" feel, I find. Nothing illustrates that better than traveling through the forests and rocky outcroppings of the Canadian Shield and having Nerves Normal, Breath Normal pounding in your ears.
