Mosaic’s cross-office sing-along

This is what 370 voices in four cities singing in unison sounds like.

Mosaic may have just struck music gold this holiday season. If the agency ever decides to call it quits on advertising, we’d suggest it take a look at the entertainment biz. They have some talented folks with pretty impressive pipes on them, as you’ll surely agree after watching its holiday spot below.┬áThe shop’s four offices came together to create one massive choir. That’s a whopping 372 voices singing a holiday tune in unison, with the help of Choir, Choir, Choir (a local Toronto group that guides friends and strangers through songs in public places). And it’s mesmerising.
