Folk-rock duo Kacy & Clayton are preparing to release a brand-new album, The Siren's Song, on Friday (Aug. 18), and they're premiering one of its tracks exclusively for readers of The Boot. Press play below to hear "This World Has Seven Wonders."

Track No. 7 (of nine) on the album, "This World Has Seven Wonders" is a perfect example of Kacy & Clayton's mix of Appalachian sounds and psychedelic folk. The melody wouldn't have sounded at all out of place among 1970s folk-pop hits, and Kacy Anderson's vocals have a slightly wispy, light quality to them.

Produced by Wilco's Jeff Tweedy and recorded at the band's Chicago, Ill., studio, by Tom Schick, The Siren's Song follows Kacy & Clayton's 2016 record Strange Country. Its the first album on which Anderson and duo partner Clayton Linthicum -- second cousins who grew up in Sasketchewan, Canada -- have incorporated electric full-band arrangements; they're joined for the project by drummer / percussionist Mike Silverman and bassist Shuyler Jansen.

"[Tweedy] knows so much about recording, music and gear that it’s overwhelming, but we have a lot in common with him in regards to our tastes of production and albums from the '60s and '70s," Anderson tells Rolling Stone. "It’s pretty inspirational to think that he wakes up every morning and works to advance the folk-country-rock medium constantly, considering he’s already released dozens of great albums. This was very motivating for us recording this album, seeing this dedication in motion."

The Siren's Song is available for pre-order via PledgeMusic. Visit KacyAndClayton.com to learn more.
