Despite their calm, clean cut exterior, the five Pennsylvania young men who make up August Burns Red produce high-energy metalcore music that calls to hard-rock ticket buyers. Formed in 2003 while in their senior year of high school, the quintet has since signed to Christian label Solid State and released six studio albums, including the most recent “Rescue & Restore.” That collection, which peaked at No. 9 on The Billboard 200, followed their 2012 holiday release entitled “August Burns Red Presents: Sleddin’ Hill, A Holiday Album.” Though the band’s tour plans have included multiple runs as part of the Vans Warped Tour, as well as headlining concerts in the US and Europe, August Burns Red has dealt with lineup changes throughout their decade-long life. Only three original members are still onboard to-date: guitarist JB Brubaker, guitarist Brent Rambler and drummer/pianist Matt Greiner. Frontman Jake Luhrs signed on in 2005, and bassist Dustin Davidson joined a year later.
