They May be Friends, but They'll Piano Duel It Out 'Til the End!
Jason Lyle Black is a pianist, but not just your average one. No, instead of doing what everyone else does, this guy plays with humor, composes mash-ups, and oh yeah, plays the piano backwards. Yes, you heard that right! For this Frozen mash-up, he and his friend Sara (they're not siblings in real life) start off traditionally, but soon turn around for some wacky and impressive piano work!
