Pentatonix

Usually, we’re not big fans of pushing the season. Twinkle lights and Rudolph? C’mon, we just took off our Halloween costumes! But Pentatonix’s cover of Leonard Cohen’s “Hallelujah” off their just-dropped new Christmas album has us jonesing for jingle bells, proof of the a capella group’s considerable talents. The young quintet started as three high school pals in Texas and got noticed with a YouTube video that quickly gained traction, landing them a winning spot on NBC’s The Sing-Off and a fast track to fame. Fast forward and the pop group, who do stunning a capella covers of artists ranging from Survivor to Ariana Grande, have two Grammys under their belts and are touring major arenas.
