Diamond Rings is the musical alter-ego of Toronto-based multiplatform artist John O (John O'Regan), first conceived in the summer of 2009. A 7" and home-made video for his first bedroom-recorded single "All Yr Songs" helped to propel Diamond Rings into the spotlight, first garnering attention from Canadian blogs like Chromewaves, and then eventually a "Best New Music" honors from Pitchfork. The 7" was issued as split with fellow Ontario musicians PS I Love You on O'Regan's own boutique label, Hype Lighter.

Diamond Rings followed suit in 2010 with two more vinyl singles and corresponding videos: a 7" for the song "Wait & See" on German-based label Tomlab in February, and a 12" single for "Show Me Your Stuff" as the first-ever release on Toronto-based One Big Silence.

Diamond Rings signed to Montreal-based Secret City Records in mid-2010 and issued a fourth vinyl single/video for the song "Something Else" in September 2010, in advance of his debut-full length Special Affections. In addition to "Something Else" Special Affections includes the previous singles "All Yr Songs" and "Wait & See," and was released in North America on October 25, 2010 by Secret City.

His second full length album, Free Dimensional, was released on 23 October, 2012. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
