Lauren Shera, Andrea Blunt and sisters Christina Bailey and Sara Bollwinkel have been dominant musical forces on their own for several years. Last November, the four united and became a super group.

Like the dictionary definition of “honeymoon,” the band honeymoon (lowercase intentional) creates sweeping harmonious moments through its music.

“It’s the perfect explanation for what happens to the four of us when we get together,” Shera says.

This Sunday at the Henry Miller Library will mark the band’s first homecoming since its origination.

The collaboration was organic: The first time the musicians played together a simple set turned into an all-day jam session.

“We wound up even writing a song together in six hours,” Shera says.

That first song the quartet penned, “Find Me,” was also the first track they recorded for an upcoming EP. As of now, the group has only written a handful of new songs as a team, so they’ve also been playing some of the old tunes they wrote separately. Honeymoon transformed “Stealth” – a finger-style song written by Shera two years ago – into a warm-bodied, soulful a cappella.

“We play our own original work and write new stuff as honeymoon,” Blunt says. Shera adds that band’s rapid songwriting method is “so easy it’s criminal.”

In May, honeymoon was invited to play the Further Fest after Grateful Dead bassist Phil Lesh heard them open for Jackie Green.

After their performance at Further, Lesh told them they made the music of “sirens and goddesses.”

“All of us had to close our jaws and realize who this man was,” Blunt says. “He’s a legend… and he said this to us.”

Later this summer, honeymoon will open three shows for folk great Mary Chapin Carpenter.

HONEYMOON plays 2pm Sunday, July 11, at the Henry Miller Library, a quarter mile south of Nepenthe Restaurant on Highway 1, Big Sur. $15 advance; $20 door. 667-2574.
