Blank Realm’s deceptively modest name belies one of the most exciting rock bands in Australia—no, make that the world. Their songs boast vocals, choruses, and fairly typical structures, but these familiar elements somehow cohere into scintillating, catchy songs devoid of corn. At a time when most rock is groaning on its deathbed, Blank Realm’s latest album, Go Easy, suggests that there’s still robust life in the old coot yet. Check the “Death Valley ’69”–like “Acting Strange” for proof. (Cairo, 507 E Mercer St,, 8 pm, all ages)
