This summer's Monster Energy Rock Allegiance Tour, featuring the international lineup of Volbeat, HIM, All That Remains and Airbourne, has unveiled several more dates of its itinerary. The trek now spans from Aug. 23 through Sept. 28.

After eight dates were revealed for the North American trek a couple weeks ago, a total of 18 shows have now been publicized. Rock Allegiance kicks off Aug. 23 in St. Paul, Minn., and runs through a Sept. 28 show in Brooklyn, N.Y.

Volbeat are currently riding high with their latest single 'The Hangman's Bodycount,' which sits atop the active rock airplay chart. The track appears on the band's latest disc, 'Outlaw Gentlemen & Shady Ladies.'

Meanwhile, HIM will be out in support of their latest disc 'Tears on Tape,' while Airbourne are promoting their latest effort, 'Black Dog Barking.' All That Remains are touring behind their 2012 disc 'A War You Cannot Win.'
