Polyvinyl has signed Portland, Oregon's 31 Knots. The band previous released a series of albums on 54-40 or Fight!. The band is described as "guitar-driven, brainy and angular indie-rock band with cool music and-surprise-great vocals" by the Village Voice and Tim Krysko referred to them as having "unpredictable, complex, and chaotic math rock sound.".

On July 12, Polyvinyl plans a domestic release of The Curse of the Longest Day EP which has previously been available only as an import. The band will follow the EP with a full length in the fall titled Talk Like Blood.
