One of the biggest musical acts to come out of Richmond, Lamb of God spent the past 15 years perfecting its heavy metal sound and garnering fans with successful albums, including 2004’s ferocious “Ashes of the Wake” and 2006’s unrelenting “Sacrament” — which earned the group a Grammy nomination for best metal performance, the first of three. The band has landed in the top 10 of the Billboard charts and toured North America relentlessly, sharing the stage with Ozzy Osbourne, Slayer and Megadeth. The group’s latest album, “Resolution,” is set to be released Jan. 24 and will more resemble the band’s more exploratory early work, such as “As the Palaces Burn,” but still give fans all the deafening, going-for-the-jugular metal they want to hear. Lamb of God performs at the National on Saturday, Jan. 22, at 7:30 p.m. $20-$25. 612-1900.
