Through several spots Spotify wanted to show how music makes us all feel and what it's like to be lost in the moment of a song.

In the 'For Music' spot  The Mill's team had the challenge of building the environment - one that moves like ocean waves, yet is still recognizable as a crowd. It had to be both incredible and realistic. CG lead Wyatt Savarese and R&D artist Brenton Rayner explain, "Massive software played a huge role in creating shots where either the wave of people was in the distance behind a foreground live action plate, or where the entire shot is CG. It's not every day you get asked to build a literal sea of people. Massive is an amazing tool and looking at the results for Spotify we're glad we went forward with it. Creating a Massive-to-Maya pipeline also allowed the Mill artists to physically light crowd simulation in a mental ray environment and achieve the look Seb was after."

West Sarokin, Mill VXF supervisor comments, "The live action footage had such a strong cohesive look of flashing lights, flares, atmosphere, deep shadows and rim lighting that we had a very solid aesthetic direction for how we wanted to make the CG look so that it worked in the piece as a whole. And having 500 enthusiastic extras dancing for the duration of the shoot gave us a fantastic crowd to build on and composite with the CG elements we created."

The Mill team worked very closely with agency and director on all spots in the campaign to come up with a creative solution, technique, look and game plan to make such a challenging project a reality.

"From shoot to ship was a mere three weeks.  An incredible amount of passion, hard work, skill and above all else creativity was needed. It's a collaboration we were thrilled to be involved in and we're all very pleased with the end result," said Sean Costelloe, The Mill's Head Of Production, New York.

So switch on, tune in and listen.
