Their sharpness and soul made PTX one of the most popular and well-known a cappella groups outside of The Barden Bellas. The vocal quintet takes a creative leap forward here—crafting originals with the same energy, detail, and richness that made their cover songs so beloved. “Sing” and “Na Na Na” show that PTX are pop maestros, creating magic with just voice, handclaps, and beatbox. They float effortlessly between styles—“Misbehavin’” takes its cues from doo-wop, “Ref” can fit in with any EDM set, and “First Things First” feels like a lost Timbaland track. To close the album, PTX include their takes on pop hits “Where Are Ü Now,” “Cheerleader,” and “Lean On.”
