At nine members strong, gypsy punks Gogol Bordello have made a career of acquainting American audiences with dub-inflected Eastern European music. Formed by lead singer Eugene Hütz in 1999, the band has toured relentlessly over the years with various lineups, showcasing its supercharged live show at both Vans Warped Tour and Bonnaroo. On its seventh and latest album, Seekers and Finders, the group of immigrants—ranging from Ukraine to Ecuador and Ethiopia—transforms global negativity into messages of self-empowerment and perseverance, like on the title track, which features Russian-born pop singer-songwriter Regina Spektor. Funky brass band Lucky Chops open Thursday’s show.
