It's "woman-with-guitar" night at Westhampton Beach Performing Arts Center as Labor Day weekend gets into full party mode Saturday. But not just any woman. Shawn Colvin, folk-pop singer-songwriter - and, yes, guitarist - brings her multi-Grammy-winning repertoire to the stage for an evening of songs that reflect her life.

The rocky relationship with her father, for instance, in "Tuff Kid": "My daddy hit me, but he couldn't quit me." Or her struggles with alcohol. "Sometimes, I still want to take the edge off," she says, a quarter-century after she quit drinking.

Then there's the hit that almost made her a rock star, "Sunny Came Home," about a woman, betrayed by her man, who burns the house down.

Well, that one's not about her. "I never set fire to my house or murdered anyone," Colvin, 54, says. We spoke to her on the road, near Boston, on tour following the release of her "Shawn Colvin Live" CD. 

Tell us about your current tour. Is it a "woman-with-guitar" show, as Westhampton Beach's website calls it?

That's pretty accurate. Just me. I try to do a fairly well-rounded selection of my songs with a few covers I've recorded.

How has your songwriting evolved? Is it any easier with more life experiences to draw from?

The landscape changes, but the process is pretty much the same. I come up with ideas the same way [often with collaborator John Leventhal]. But, yeah, life affects what I write about. For one thing, I'm a mom now.

Speaking of motherhood, you took time off before your "These Four Walls" CD in 2006. Was it a challenge getting back to work, or does the album title speak to a kind of cabin fever?

To me, that album is more about putting down roots. It was the first solo I'd done since my daughter was born. [Callie is now 12.] Recording it was a little different, though. I couldn't work from home. Too distracted, too domesticated, I guess. [Laughs.]

Did you feel any pressure to match your success after "Sunny Came Home" won song and record of the year Grammys? Did you try to become more pop?

It created pressure, sure. But we knew it would be futile to force anything. It was nice to have such a success. I wouldn't mind having another.

I read that you learned guitar from your dad, a Kingston Trio fan. Who were some of your other folk influences, aside from Dylan?

Yes, my dad taught me my first few chords. I forget which Kingston Trio song. After that, the Beatles were really important to me. And a few years later, Joni Mitchell, Laura Niro, Paul Simon. And Dylan.
