BIGBANG, a second-generation K-pop boy band and one of the most popular in the history of the genre, have returned with their first song in four years, their first release since Seungri left the band and the remaining members fulfilled South Korea’s mandatory military service. “Still Life” marks a long-awaited return to the spotlight for T.O.P, Taeyang, G-Dragon and Daesung—their dreamy harmonies are well-rounded, more nostalgic than ever—and the piano-rock power ballad is a long, wistful reminder of the group’s strengths. This is a band that has been through a lot, and they’re stronger because of it; in a particularly poignant moment, rapper T.O.P offers this assurance: “I’m going to change more than before/To become a good person even more.”
