The boys of Tomorrow X Together, or TXT, began as the only act in the immediate orbit of the K-pop titans BTS. Created by the masterminds at Big Hit Music, the group has always had to manage certain expectations — even as a standout of K-pop's fourth generation, it seemed to be searching for an identity separate from the art-rap reputation established by its label. TXT's most recent album, The Name Chapter: Freefall, captures its sprawling ambitions: from new wave-y retro-pop to bassy, beaming dance music; the mildly grungy to flat-out nu metal. The group's performance of three songs from the release for Tiny Desk Korea brings these modes into something resembling a coherent vision, playing into its signature rock band aesthetics while giving their music a soft-focus feel. With two guitarists at their backs, seated all in a row, the boys seem in their element.
