Australian rock quartet Howling Bells has signed to Nettwerk Music Group, and the band is set to release its sophomore album and North American debut, "Radio Wars," on July 28th in the U.S. and Canada. The album's first single, "Cities Burning Down," will be out June 2nd on iTunes.

The UK-based group - comprised of siblings Juanita Stein on vocals and guitarist Joel Stein, bassist Brendan Picchio and drummer Glenn Moule -- are set to open for Coldplay on a North American tour this May and June.

For "Radio Wars" the band partnered with producer Dan Grech-Marguerat, who engineered records alongside Nigel Godrich for Radiohead, Air and Paul McCartney, among others.

Howling Bells formed in Australia in 2004 and shortly after moved to London, where they recorded their 2006 self-titled debut with producer Ken Nelson (Coldplay). Driven by singles like "Setting Sun" and "Low Happening," the success of Howling Bells saw the foursome tour with the likes of The Killers and Placebo in Europe and Snow Patrol in Australia.
