Listen to Kacey Musgraves on iHeartRadio

Kacey Musgraves is sharing new music with a national television audience.  The country star is slated to be the musical guest Thursday on NBC's "The Tonight Show Starring Jimmy Fallon." 

But instead of performing her current single, "Keep It To Your Self," she'll give the TV debut of the new tune "The Trailer Song."  The track is not from her Grammy-winning album Same Trailer Different Park.  

The "Tonight Show" appearance comes just ahead of her "CMT Crossroads" premiere.  The episode, featuring Musgraves with pop star Katy Perry, will have its premiere on CMT Friday at 10:00 p.m. Eastern. 

Meanwhile, more new music could be on the way from Kacey courtesy of a rock legend.  Rolling Stone says Musgraves is one of several artists the Beach Boys' Brian Wilson has tapped for his latest studio project.  She reportedly teamed up with Wilson on a song called "Sharing a New Day," which the publication describes as "sassy."  However, the Musgraves collaboration hasn't yet been confirmed for the release.
