They've been close friends for nearly 15 years, and that's why they say they can work together so well.  And they're two couples.

They formed their group last year, and although they are based in Nashville, they're all from west of there.  Hawaii.  California.  Texas.  And Iowa.  So when they travel away from work, they're almost all travelling west.  Hence the group name.

It's their debut single, from their forthcoming debut studio album.  Vote Yea or Nay for Gone West,  'What Could Have Been'.
