ABC announced today a new music series Greatest Hits. Each episode will highlight a five-year period celebrating the biggest hits from that time, hosted by Arsenio Hall and Kelsea Ballerini. Each week, iconic music artists, as well as today’s music chart-toppers, will take the stage and perform the songs that defined the 1980s, 1990s and 2000s. The six-episode series will feature special solo performances, never-before-seen duets and incredible tributes on Greatest Hits, premiering Thursday, June 30(9:00-10:00 p.m. EDT), on ABC.
