Amstel Light is spreading a little holiday cheer and music through the Union Station subway stop in New York City. The beer brand has teamed with the New York City Symphony to perform holiday tunes using Amstel Light bottles as instruments. The bottles are filled with various levels of the beer to produce the correct tune. They will be performing from 12:30-2pm today at Union Square. I've never heard of such a thing being used before as an advertising tactic, but I like it. I like it a lot.
