After Karmin put their cover of Chris Brown’s “Look At Me Now” on YouTube a few weeks ago, the video quickly became a viral sensation and the engaged duo found themselves performing the song on The Ellen DeGeneres Show. Fast-forward a week later and the couple is taking on Lil Wayne & Cory Gunz’s “6 Foot 7 Foot” for their newest popular song rendition. Just as with Busta Rhymes’s, Brown’s and Wayne’s verses on “Look At Me Now,” Amy delivers the lyrics of “6 Foot 7 Foot” with impressive charisma, rhythm and speed. Also, she and her fiancé Nick break into and out of the song by incorporating the 1956 track from which the song was sampled: Harry Belafonte’s “Day-O (Banana Boat Song).” The duo is certainly entertaining and talented, so it will be very interesting to see what they make of their success.
