Incredible A Capella Medley of Michael Jackson’s Greatest Hits

The a capella group Pentatonix performs an incredible tribute covering all of the King of Pop's greatest hits, from the Jackson 5 to Thriller and beyond.

Pentatonix (winners of The Sing-Off in 2011), an a capella group from Arlington, Texas, shows off their vocal chops in this amazing vocals-only rendition of all of MJ's greatest hits, in honor of the anniversary of his June 25th 2009 death. From "I Want You Back" all the way to "Thriller," "The Man in the Moon," "Billie Jean," and many more, the performance shows off both Pentatonix' incredible harmonizing skills and the phenomenal talent of Michael Jackson.
