If there’s one thing that Jónsi’s music invokes, it’s Iceland: the chaotic beauty, the forbidding and unstatic geology, the vast volcanic expanse. Maybe that’s why the Sigur Rós frontman’s first (non-instrumental) solo album sounds as though it could be the soundtrack to an IMAX film about his native country. With their triumphal orchestral richness, “Sinking Friendships,’’ “Tornado,’’ and “Around Us’’ all conjure full-field-of-vision shots that swirl around the tops of glaciers and convey the dizzying yawp hundreds of feet down to the ocean. But while “Go’’ occasionally possesses the scope of IMAX (and Sigur Rós), it never develops the depth or grandeur. That may be intentional, though, since Jónsi seems determined to reveal a playfulness that he usually keeps hidden. The itchy, glitchy thump-thump-thump-thump beats of “Go Do’’ and “Animal Arithmetic’’ are practically a snare hit or two away from transforming into mind-expanding dance songs, while “Boy Lilikoi’’ is fitted out with so many chittering sounds that it sounds like a paradisical rain forest. Still, “Go’’ is modestly transporting, at least until the lights come up and you head toward the space program exhibit. (Out tomorrow)
