The great metal band Mastodon finally return to Nashville after recording and releasing their sixth studio album, Once More ‘Round the Sun, in nearby Franklin, Tennessee, and this time around they’ve brought some friends, Norwegian metal band Kvelertak and, a band that I’ve really been getting into in the past several months, the French band Gojira. When I was looking at going to the concert, I actually hadn’t heard of Kvelertak, but a friend of mine described them to me as “blackened hard rock” before the show started. However, I was excited just to see Mastodon and Gojira on the same bill, and I was not disappointed in the least.
