Miranda Lambert has recorded a brand new song that's not available on any of her albums.

The country star wrote 'Roots and Wings' especially for a series of Ram Trucks ads that will air across television, print, digital and social media. The campaign represents the next phase of a partnership between Lambert and Ram Trucks that was first announced in November of 2014.

The commercial spot draws on Lambert's life story, using locations that are part of her real life, as well as family photos.

"I am very inspired by what the Ram brand stands for -- being who you are, working hard, staying true to your roots,” Lambert says in a press release. “I wanted to write a song that would represent all of those things. ‘Roots and Wings’ is personal to me about where I come from and where I am going. The guys at Ram really made the lyrics come to life with the imagery and I hope it speaks to people the way it does to me."

“Miranda Lambert is a perfect partner for Ram,” adds Robert Hegbloom, President and Chief Executive Officer, Ram Brand, FCA – North America. “In our very first meeting we saw the connections between her core values and those of the Ram Truck brand -- common traits like hard working, determined, goal-oriented, tough and a driving purpose to perform brilliantly at the highest levels. She’s been around trucks her entire life, from being born on a farm to owning a ranch now, and she lives her life by her own rules just like so many of our Ram Truck owners.”
