Arriving in late 2020, We Need a Little Christmas is the a cappella pop group's seventh full-length overall and fourth holiday album. Although it's a set that favors skittish exuberance over wholeheartedness or nostalgia, rare exceptions include the one original track here, album highlight "Thank You," a tribute to loved ones who made a challenging year more bearable. The remaining dozen covers range from Ariana Grande’s "Santa Tell Me" to an uneven "Amazing Grace" and season-appropriate show tunes such as "When You Wish Upon a Star" (Pinocchio), "Once Upon a December" (Anastasia), and a spirited "My Favorite Things" (The Sound of Music) with the reliable Kirstie Maldonado on lead. Though neither needed the other, "White Christmas" sees Pentatonix joined by an archival recording of Bing Crosby (as well as the London Symphony Orchestra) before "Season of Love" (Rent) closes the mostly playful set with a loyal rendition and a cathartically earnest note.
