South Korean boy band P1Harmony's sixth EP Harmony: All In -- their third in the extended-play trilogy -- continued the group's steady rise up the international charts, marking the first appearance on the main U.S. album chart. P1H's rousing blend of pop melody, hip-hop edge, and dance-friendly energy keeps most of All In on the dancefloor, whether through the throb of "JUMP," the deep bass rumble of "New Classic," or the frantic electro "rum-pum-pum" of the throwback anthem "Heartbeat Drum." Falling between the more aggressive second installment Harmony: Set In and the relatively calm Harmony: Zero In, All In strikes an ideal balance and might be the best of the triptych. ~ Neil Z. Yeung
