Kassi Ashton

Newcomer Ashton brings a little swagger in her contribution to Urban's song "Drop Top," off the upcoming 'Graffiti U' album.

So how did Kassi Ashton end up on his Graffiti U album?

Urban's upcoming album, 'Graffiti U', will feature a number of collaborations.

Ashton has been writing genre-bending songs since the age of 15.

She is one of very few artists able to offer the kids at St. Jude Children's Research Hospital first-person hope.

The song is the one song she knew she had to write, just like the town that inspired it was the one place she knew she had to leave.
