The latest addition to the 2007 Warped Tour is Hertfordshire, UK-based punk band Gallows.
Besides joining a roster which to date includes Bad Religion, Tiger Army, Paramore and others, the tour marks the band's first ever trip Stateside.

Update: The band's proper name is Gallows. Thanks to Alex for the correction.
