Dar Williams is set for a 'Promised' landing on LI

Dar Williams is calling from Grand Central Station, where she just missed a train. That's OK, though - the folksinger-songwriter, children's novelist, wife and mother needs to catch her breath every so often.

Although her last album dropped in 2008, Williams has kept busy with a couple of guest appearances, most notably on the "Songs of the Spectrum" compilation, which raises awareness and money for different autism charities. She also helped out her pal Patty Larkin on Larkin's acoustic revisiting of her older songs on the recent "25" album.

"I'm a woman about town," says Williams, who makes her way to the Landmark Theater in Port Washington tomorrow. "That's the way to do it."

How did you hook up with the "SOS" autism fundraiser?

There's this wonderful bass player in New York named Mike Visceglia who was involved. He asked me about three times . . . and then I heard some of the demos from the CD and knew I wanted to be a part of it. I thought it was musically worth it as well as socially worth it.

Your most recent album, "Promised Land," was produced by Brad Wood, more of a rock and roll guy. How did that feel?

Every producer's sensibility is different. But "Promised Land" was the first album I wrote mostly at home as opposed to mostly on the road, and in some ways it had a little bit more unity than some of my other albums.

What's next musically?

I took six months off to work on a few creative projects . . . so what's next is whatever the world receives.[Laughs] . . . I am working on an album that I'll record next January.

What can folks expect at the Port Washington show?

I'm going to try and have a couple of new songs ready - I haven't come out with a new one in a long time, so I'm hoping to have these ready for the show. I still find that I like to do songs from "Promised Land," but I always do something from all the albums.

You grew up in Chappaqua . . . anywhere near where the Clintons settled?

Other side of the tracks.
