Us The Duo artists Carissa and Michael Alvarado are known as the first musicians to become established via Vine. The married duo posted their first #6SecondCover vines in 2013 and are closing in on 5 million Vine followers. Since then, they’ve scored a record deal with Republic Records, recorded two studio albums, went on tour with Oprah, and were invited to The White House in 2015 to help launch Michelle Obama’s Better Make Room campaign. Their annual end-of-the-year mashups of top hits in 3.5 minutes got millions of views and acts like a nostalgia time capsule for a short attention span.
