In a gracious gesture, Killswitch Engage are donating toward the relief efforts in tornado-ravaged Oklahoma by offering a portion of the proceeds from tonight's performance at the Diamond Ballroom in Oklahoma City to the Regional Food Bank of Oklahoma.

The group isn't stopping there either, as they reportedly are designing a special Killswitch Engage t-shirt and will donate 100 percent of the proceeds of sales from the shirt to the Regional Food Bank of Oklahoma as well. Details surrounding the t-shirt have not been revealed as of yet, so keep a check on the band's social networking sites for updates. Those wishing to donate to the Regional Food Bank of Oklahoma just as Killswitch Engage are doing may do so at this location.

Tonight's Oklahoma City stop (May 30) is the first date on Killswitch Engage's 'Disarm the Descent' tour. The trek also features Darkest Hour, the Word Alive, Miss May I and Affiance. To see the full itinerary of Killswitch Engage shows, click here.
