Zach Bryan's newest musical endeavors appear to include some out-of-genre, outside-the-box collaborations.

On Sunday night (Sept. 17), the singer hopped on social media to share a trio of new songs, freshly written and recorded during a productive period of camping, collaborating and sequestering himself in a studio. Two of the friends on hand with him during this session were indie singer-songwriter Noah Kahan and noted folk group Bon Iver, and Bryan connected profoundly with both acts, he says in the caption of his post.

"Locked myself in a studio all week, wrote through a notebook, walked around with people I love in the city then went campin, felt restful and hopeful, thankful for breathing no matter the day, just grateful," Bryan writes in sharing the new music. "Thank you to [Bon Iver] and [Noah Kahan.]"

On Instagram, the three songs are posted as a video carousel; on Twitter, Bryan isolated each one as its own post, delineating which song featured Bon Iver and which featured Kahan, and saying to each collaborating act, "Come back soon ... you have a friend for life."

"Them boys of faith," Bryan also writes on social media, in what appears to be a nod to a lyric or the title of the song he cut with Bon Iver.

In addition to the two collabs, Bryan also shared a new solo song. He didn't tell fans the title of any of the songs, but in the caption of the third, solo song, he writes: "A pool stick I was gifted from him."

The new songs Bryan is teasing follow his newly-released, self-titled album, which he dropped in late August. That album debuted at the top of the Billboard 200 albums chart, and one of the songs on the track list, a collaboration with Kacey Musgraves called "I Remember Everything," topped the Billboard Hot 100.

Every Country Music Hit to Top the Billboard Hot 100 Chart

In 2023, three songs have hit No. 1 on both the all-genre Billboard Hot 100 and Billboard's Country Airplay chart. Before that, just 20 songs had accomplished this. Here's the full list of those songs, including the five artists who have done it twice.

Oliver Anthony is the latest to accomplish this feat: In August 2023, his song "Rich Men North of Richmond" debuted at No. 1 on both charts.

26 Country Stars You Won't Believe Aren't Grand Ole Opry Members

Fifteen living CMA or ACM Entertainers of the Year are not members of the Grand Ole Opry, and a few of them barely recognize the vaunted stage. George Strait, Kenny Chesney and Willie Nelson are three legends who rarely play the Grand Ole Opry. Why?

That answer is often difficult to determine, but this list suggests reasons where appropriate. Membership into the Grand Ole Opry comes with an obligation to play the show frequently, but that's often set aside (Barbara Mandrell is an inactive member, for example). Only living artists are considered, and once a member dies, they are no longer a member.

As of 2023, there are more than 70 members of the Grand Ole Opry. Historically, nearly 250 men, women and groups were members — so, it's a select group that excludes several Country Music Hall of Famers.
