Tribal DDB Amsterdam rejoins Phillips for "Obsession with Sound," an interactive music experience that shows off the brand's audio range. The campaign, which is live on the Facebook page, lets you listen to the Grammy-award winning Metropole Orchestra, and single out each musician to hear details of their individual tracks. Singling out a musician also gives you access to their musical tendencies, background and personal Twitter and blog feeds. The idea is to "hear every detail" -- something that Phillips says its range of speakers can also achieve.

Alongside the campaign, there's also a contest that challenges entrants to create their own compositions, which will then be judged by a distinguished jury. The winning track will be arranged and played by the Metropole Orchestra and recorded in a music video.

This follows a string of notable projects from Tribal DDB for Phillips, including the Cannes Grand Prix-winning "Carousel" and the ambitious "Parallel Lines" films.
