Andrew Kelham of Rock Sound gave the album a nine out of ten, and wrote that "With a why-just-write-a-song-when-you-can-write-an-epic attitude, the eight songs on their second record are distinguished, articulate and immersive as their juddering post-hardcore clashes with moments of Explosions in the Sky rivalling tenderness and Mogwai-esque grandeur.

" Writing for Alternative Press, Brian Shultz gave the album four out of five stars and said that the group has, "quietly refined their craft over the last few years into an incredibly cathartic and sporadically chilling mode.

Their screamo peers–past or present–should be more than envious." Old Pride was released on vinyl in June 2010 as a joint release through Topshelf Records and Mayfly Records. In support of the album, Pianos Become The Teeth toured the US with Touché Amoré and Lemuria.

In October 2010, Pianos Become The Teeth released a split EP with The Saddest Landscape through Just Say No!
