The statement is false. While Yo-Yo Ma's "Soul of the Tango" album helped to popularize tango music in the United States and around the world, it did not contribute to the elevation of tango from its humble roots.
Tango music has a rich history and cultural significance in Argentina and Uruguay, where it originated in the late 19th century. Tango has always been a popular and well-respected musical genre in these countries, and has been performed and celebrated for over a century. So, Yo-Yo Ma's album did not elevate tango from its humble roots, but it did help to introduce this beautiful and passionate music to new audiences around the world.
