Listen to Us The Duo Radio on iHeartRadio

Once upon a time, a boy and a girl from opposite sides of the country randomly met on the set of a music video. They fell in love, got married, and combined their passion and talent to form a fast-growing music career, writing and recording their own songs together. No, this isn't just a fairy tale. It's the true story of Michael and Carissa - of course, you might know them as Us The Duo

Their journey started three years ago, and today they have released their second album No Matter Where You Are. Now, they are touring the country, spreading their music and unique story (while sharing a few viral YouTube videos and Vines along the way).

Us The Duo stopped by iHeartRadio Headquarters when they were in New York City recently, where they treated us to a performance and revealed the top three reasons why 2 is better than 1.

Check out "Top Three" with Us The Duo below.
