Despite a moniker that invokes, among other images, a gentle spirit, Lamb of God is actually a wolf in sheep's clothing. In fact, the metal quintet is so ferocious that it makes other metal bands look like "Sesame Street." Lamb of God's two-decades-long career has been marked with ups (a major label deal plus three Grammy nominations) and downs (lead singer Randy Blythe's arrest — and subsequent acquittal — for manslaughter in the Czech Republic after a fan died from an injury sustained at a LOG concert). What has remained constant is the group's reputation for quality tunes and blistering shows that have elevated it above the rest the pack. With The Acacia Strain and Decapitated.
Lamb of God performs Thursday, June 13, 7:45 p.m. at Water Street Music Hall, 204 N Water St. $25.75-$30.90. waterstreetmusic.com.
