Everyone is doing Disney's Frozen videos and covers lately, but this has to be the best yet: Watch Brian Hull singing Let It Go impersonating 21 classic Disney and Pixar (which is now Disney too) characters, which is extremely hard to do while singing. Really amazing talent. He really nailed it.
The list of characters: Captain Barbosa and Jack Sparrow (from Pirates of the Caribbean), Roz and Mike Wazowksi (from Monsters Inc), Lumiere, Cogsworth (from Beauty and the Beast), Dug and Alpha, (from Up), Kaa (the Jungle Book), Sebastian and Scuttle (The Little Mermaid), Scar, Pumbaa and Timon (The Lion King), Ray (the Princess and the Frog), and the classics Pete, Winnie the Pooh, Tigger, Mickey, Minnie—holy crap, I'm surprised how well he hit this one—and Goofy.
Somebody at Disney should hire Brian right now.
