These two terrific hard rock bands bring their co-headlining tour to Jacobs Pavilion at Nautica. Known for albums such as 2012's L'Enfant Sauvage and 2016's Magma, Gojira returned in 2021 with Fortitude. Last year, it released the anthemic single "Our Time Is Now," a tune featuring highly technical guitar work and menacing vocals. Not to be outdone, Mastodon has had its music appear in Game of Thrones and in DC Comics films. Its most recent album, Hushed and Grim, yielded the frenetic single "Pushing the Tides." Lorna Shore, a group known for its intense live performances, opens. The concert begins at 6 p.m.
