Grizzly Bear again? Ah yeah, again and again. With two songs leaked from next month’s Shields, the ursine squad are the only contenders to take Ariel Pink’s crown for my favorite album of the year involving guitars. Even though their piano lines and layered vocal harmonies seem to provide the music with most of its emotional gravity. The last minute or so of “Yet Again” is a distorted squall of guitars, but somehow they never lose control. Grizzly Bear’s music is meticulous, attuned to the elements, angels tap dancing on the head of a pin.
