Fresh off the heels of the release of their video for 'Who'll Buy My Memories,' Willie Nelson and his sister Bobbie Nelson have released another video, this one for their song 'Laws of Nature.'

The new video also features the sibling duo performing the song in a home studio, but this time, they've added in scenes of beautiful meadows and farmland, calling to Nelson's deep foots in the farming community.

'Laws of Nature' comes off of the duo's collaborative album 'December Day: Willie's Stash, Vol. 1,' which features a mix of the country legend's greatest hits, deep cuts, covers and some new songs.

For 'Laws of Nature,' Nelson takes a turn acting as a voice for the crops in the field singing, "I get my water from the rain / And if it don’t rain, I’ll die / Stormy weather saves my life / Sometimes I laugh and wonder why."

'December Day' is available for download on iTunes and Amazon.
