The Sword—singer-guitarist John D. Cronise, bassist Bryan Richie, guitarist Kyle Shutt and drummer Jimmy Vela—have been making quality heavy metal since forming in Austin, Texas, in 2003. While some have labeled the band’s genre doom metal, stoner rock or even hipster metal, make no mistake, that influenced by Black Sabbath and Slayer, the Sword straight-up rock. They’re back out on the road again in supports of their fourth LP, the acclaimed Apocryphon (stream it below), released last year, which, with its increased focus on songwriting, is “more diverse musically…. It’s a little more a rock album than previous records,” says Cronise. Fortunately their current tour brings the Sword (above, doing “Freya” at Bonnaroo) to Music Hall of Williamsburg on Sunday.
