Pentatonix -- The World Tour

The vocal group that famously won the third season of NBC's The Sing-Off, brings its current trek, simply dubbed World Tour, to Blossom. The group's most recent album, Holidays Around the World, came out last year and became the group’s ninth Top 10 entry on Billboard’s Top Holiday Albums Chart. Since it's not the season for Christmas music, expect to hear songs from its extensive catalog of originals and covers at tonight's show, which begins at 8.
