Thirty Seconds to Mars’ maximalist rock has always been a vehicle for big ideas: Jared Leto and crew explore themes of war and peace, sexuality, freedom, and faith through concept albums and glossy videos. But the widescreen focus of AMERICA may provide the group’s broadest statement yet. In an attempt to survey, as he put it, “the good, bad, and the ugly” about his homeland, Leto even hitchhiked cross-country to promote the record. Guest turns from A$AP Rocky (“One Track Mind”) and Halsey (“Love Is Madness”) both draw parallels between romance and insanity. But Leto seems to have a different form of madness in mind on “Hail to the Victor” as he cries, “Another night, another war/Another ‘What are we fighting for?’/Is everybody out here crazy?”
