Publicis Conseil introduces BNP Paribas' "Hello Bank!" which claim to be Europe's first fully-digital mobile bank, with a smart orchestra stunt. Created in collaboration with master production company B-Reel and the Czech National Symphony Orchestra, the campaign brought together the talents from the musical and tech world for a one-of-a-kind performance by the orchestra that showed just what you could do with just your mobile phone. Taped during a performance in Prague, and led by conductor Libor Pesek, the outfit's 60 musicians put aside their instruments for a special performance of "Carmen."
