Cosmote 'harmony' by Bold Ogilvy

A choir of mobile, landline phones and laptops produces a melody to illustrate that every mix between any two or all three means of communication is possible through Greece's leading mobile telecommunications provider.

The film was shot featuring a live choir in the biggest music hall in Athens to provide the best sound and acoustics.

The choir was trained by a choreographer and a team of musicians wrote an original music score.

The film pays-off with the phrase: "The most harmonic combinations between mobile, landline phones and internet on the go".
