On the December 18th episode of MBN's 'What's Up', the cast of the show performed a stunning rock cover of Park Bom's solo hit, "You and I"! The episode divided up the freshman musical students into two competing teams by their instructor and asked them to come up with a rearrangement of the 2010 hit song. On the 'B team' were Im Joo Hwan, Kim Jiwon, and Daesung, who incorporated rock elements to the song with faster beats and thrumming rap. The addition of Daesung's powerful vocals adds a dimension to the song never thought of. The 'A team' took a slightly different route by opting to express the story of lovers by performing it as a duet. Check it out below! Tip: Amelia
