Over their decade-plus tenure as Underoath, the gold-certified hardcore sextet have played Nashville a multitude of times. But this week’s performance will be noticeably different than every one prior. Perhaps most significant will be the absence of lone original drummer and vocalist Aaron Gillespie, who left the band recently to give his undivided attention to The Almost, his Hills-ready rock band. Thankfully, Gillespie has been replaced with the equally capable Daniel Davison (ex-Norma Jean), whose rhythmic dexterity recalls that of Botch’s Tim Latona or Fugazi’s Brendan Canty. Indeed, Davison’s addition has been credited by his new bandmates with helping them unleash a sound they’ve been hunting for years: a more visceral, encompassing marriage of atmosphere, punk rock and metal that comes together swimmingly on their latest effort, Ø (Disambiguation). Said another way, should you need to bang your skull on the heels of Thanksgiving, Rocketown will be the place to do it.
