Mavie Marcos is an American singer/songwriter currently residing near San Francisco, California. Mavie is a part of the group Andain, known from the 3 tracks: 'Summer Calling', 'Beautiful Things' and 'Promises'.

The first 2 have featured on Tiësto's 'In Search Of Sunrise' series and because Tiësto was playing the tracks from Andain so often, people thought he was a part of it.

After a long silence, Andain has come back in 2011 with the 3rd track 'Promises'.
