This Boston band loads its latest album, Amplify, with songs that go beyond its reggae roots, borrowing from reggaeton, hip-hop and other genres without compromising its signature sound. They’ve been around for more than a decade but recently went through a considerable lineup change — bassist Scott Palmer died in 2006. At that time, the band almost disintegrated, leaving only drummer Tommy Benedetti and singer-songwriter Elliot Martin to lead the current ensemble. John Brown’s Body are touring in support of Amplify and Re-Amplify, a collection of remixes that takes their music in yet another inspired direction. Public Property and Tropidelic open at 8:30 p.m. at the Beachland Ballroom (15711 Waterloo Rd., 216.383.1124). Tickets: $12 advance, $14 day of show. — Ernest Barteldes
