Singer and pianist Norah Jones, whose 2002 solo album "Come Away with Me" sold more than 11 million copies, has decided to share the spotlight for her new album.

The Grammy Award-winning Ms. Jones has formed a country-roots trio called Puss N Boots, along with her friends singer-drummer Sasha Dobson and bassist-singer Catherine Popper.

The debut album from Puss N Boots, titled "No Fools, No Fun," is out July 15 from Blue Note Records, which is owned by Vivendi SA's Universal Music Group. The album features original compositions from each member of the band as well as covers of songs made famous by Neil Young, George Jones, Johnny Cash and others.

According to Nielsen SoundScan, Ms. Jones's most-recent solo album, the 2012 release "Little Broken Hearts," has sold more than 448,000 copies. Ms. Jones's two albums with another band, the Little Willies, sold 176,000 copies and 39,000 copies.

About seven years ago, Ms. Jones and Ms. Dobson began playing in small venues in Brooklyn, N.Y., to practice guitar, and the pair were later joined by Ms. Popper. After several years of occasional performances, "We finally decided, 'Wow, we kinda sound like a band finally after all this time; let's make a record,' " Ms. Jones said in an interview with The Wall Street Journal.

Ms. Dobson has released solo jazz recordings, and Ms.Popper has played with rockers Jack White, Ryan Adams and others.

Ms. Dobson said that the fact that Ms. Jones is much more famous than her band mates hasn't thrown off the group's chemistry. "It's challenging when there are three people making decisions that normally one person makes," Ms. Dobson said, adding "in some ways it's so much better because it's less pressure."

Zach Hochkeppel, senior vice president of marketing at Blue Note Records, said that Puss N Boots is taking a grass-roots approach to finding an audience, and the band is playing venues that are far smaller than the places Ms. Jones would book as an established solo artist. He said he doesn't expect country radio to feature the band, since the format is more focused on pop acts, but he plans to court open-minded country music websites. "We're really going after a subset of Norah's audience," Mr. Hochkeppel said.

Side projects like Puss N Boots offer opportunities to stretch creatively, according to Ms. Jones. "For me, I like to play music--rather than waiting around between solo projects," Ms. Jones said. "I love playing with my friends, I wouldn't be playing guitar if it wasn't for this band. It's just fun to make music with a variety of people."
