LOS ANGELES >> Kate Hudson is sitting on a folding chair in a crowded storage closet when suddenly the voice of Kate Hudson comes booming through the wall. The 45-year-old singer and actor is in a Fashion District studio on a recent morning to shoot a music video for “Right on Time,” a recently released bonus track from a new deluxe edition of her 2024 debut album, “Glorious.” (The closet offers some quiet for a chat as the video crew sets up.) A stately ballad that showcases her soaring vocals, “Right on Time” is about Hudson’s movie-star mother, Goldie Hawn, and right now it’s bringing a tear to the eye of the woman who wrote it.

“This song makes me emotional,” Hudson says, tilting her head toward the sound. “It’s my mommy, you know?”

Raised between Los Angeles and Colorado by Hawn and Hawn’s longtime partner, actor Kurt Russell, Hudson broke out in Hollywood with her role as a wise if idealistic groupie named Penny Lane in 2000’s rock-obsessed “Almost Famous.” Since then she’s appeared in rom-coms and action films and whodunits, hawked vodka and activewear and hosted a podcast with her brother (and fellow actor) Oliver; she’s also had high-profile relationships with Chris Robinson of the Black Crowes and Muse frontman Matt Bellamy.

Yet the guitar-heavy “Glorious” provides the first look at a natural musician who dabbled in private for years before finally getting up the courage to cut a record. Hudson — whose biological father, Bill Hudson, scored a string of pop hits in a trio with his brothers in the ‘70s — wrote and recorded the LP with the veteran producer Linda Perry and with Hudson’s fiancé, Danny Fujikawa, with whom Hudson shares a 6-year-old daughter. (She also has two older sons.) As she sips bone broth from a wine tumbler, Hudson listens to herself singing about Hawn’s showbiz origin story in the next room: “She drove a hundred miles to Baltimore/ In a busted Caddy with holes in the floor.”

Q: Is that lyric true?

A: Oh, for sure. She used to wrap her feet because she had all these holes in the bottom of the Cadillac — it was her dad’s car — and so she wrapped her feet while she drove to dance class. When she’d get there, she’d have to thaw them out in warm water because they were frozen.

Q: Why’d you want to write about your mother?

A: It just sort of happened. Linda had to take a phone call, and so she went out and I was working on this thing on the piano. She came back and she’s like, “That’s really good — what are you doing?” I said, “I don’t know, I just started writing it. It feels like my mom.”

Q: People don’t write enough songs about parents. Tons of songs about kids — not as many about parents.

A: As a daughter, I think we’re supposed to carry on the stories of our parents. And her story is amazing — how wild her stardom was for this little girl who came from a duplex house in Takoma Park, Md. Sometimes I think part of what’s happening in our culture is we’re losing sight of the three-generational household. My grandma — my mom’s mom — she lived with us when I grew up, and there’s something about going in your grandma’s room and hearing her stories and understanding your history. I live seven blocks from my mom now, and she comes over every day.

Q: You get a lot of vivid detail into “Right on Time.”

A: “Truck stop baby, won’t you dance for me?/ These 18-wheelers ain’t nothin’ to see.”

Q: Good lyric.

A: My mom used to dance at truck stops in Jersey. She would go-go dance in cages. Well, she did a couple. Then she was like, “I don’t think I want to do this — I’m going to New York.”

Q: The song builds to a big climax, but for a while it’s just you and a string arrangement.

A: When I listen to it, I get lost more in the story than in the production.

Q: That’s the goal for a songwriter, right?

A: I mean, I get obsessed with production. I went deep into [Jack] Antonoff over Christmas. The way he plays with sound and how it moves back to front — it’s actually incredibly emotional to me. You know what song I didn’t know he did? The Taylor [Swift] and Zayn song [“I Don’t Wanna Live Forever”]. There’s something about the production of that song — the way he plays with pulling it back. I listen to music like a dancer, so it’s how my body responds to it.

Q: Is your daughter a Swiftie?

A: Hardcore. We went to the Eras tour. She tried so hard to stay up but halfway through she was in my arms. It was late.
