Two of America’s top singer-songwriters, Karla Bonoff and Livingston Taylor, are touring together.

You won’t know quite what to expect at their concert, “Home for the Holidays,” 7:30 p.m. Dec. 8, Musikfest Cafe, SteelStacks, Bethlehem, except that they are presenting a balance of their own songs and Christmas favorites.

“I’ve never done a holiday tour. I’m not sure what people want to hear. It may vary from place to place,” says Bonoff in a phone interview from her home in Santa Barbara, Calif.

“It won’t be formal. We want people to feel like they are in the living room with us,” Bonoff says.

“This will be Christmas-themed, not a Christmas show. We are not going to forgo songs we are known for to sing ‘Joy to the World,’” says Taylor in a phone interview from his car on the way to the airport for a trip to Martha’s Vineyard.

Taylor agrees with Bonoff that the concert will be easy-going: “I don’t have a set list yet. If it all fell on my shoulders I could do it alone, but since I am sharing the stage with one of the great singer-songwriters, it will be an exceptionally good time.”

Taylor describes his performances as a “smörgåsbord, where you can take from them what you want.

“Some people need to listen and some people need to laugh. I am very relaxed and informal as a person. People are surprised that I am more comfortable and funnier than they expect.”

Bonoff and Taylor will do separate sets so they can play some of their fans’ favorites. Bonoff will perform with Sean McCue. Taylor will play alone. Then, the three of them will do a set together.

Bonoff, McCue and maybe Taylor will play piano as well as guitar.

As with so many projects, “Home for the Holidays” was a result of the coronoavirus (COVID-19) pandemic shutdown.

“We were looking for something to do,” says Bonoff. “We had so much time when we were not touring. We did one Christmas song, then two, three and four.”

Bonoff released her album, “Silent Night,” in 2020, which McCue produced. She was pleasantly surprised by its success, which included a spot on a New York Times list of notable Christmas albums. The album led to the tour and a re-connection with Taylor, with whom she has performed in the past.

“When I thought of a tour, Liv came to mind, and he said, ‘Yeah. I’m in,’” Bonoff says.

The SteelStacks concert is the third of a 12-date tour.

Bonoff has been playing the guitar since she was 15. She grew up in southern California, and was part of the Laurel Canyon music scene that included James Taylor, Joni Mitchell, David Crosby, Stephen Stills, Graham Nash, Neil Young and future members of the Eagles.

Linda Ronstadt recorded three of Bonoff’s songs on her million-selling album, “Hasten Down the Wind” (1976), including “Someone To Lay Down Beside Me,” “Lose Again” and “If He’s Ever Near.” Bonoff recorded “All My Life” (1989) as a duet with Ronstadt and Aaron Neville.

Bonoff’s song “Home” was covered by Bonnie Raitt, “Tell Me Why” by Wynonna Judd, and “Isn’t It Always Love” by Lynn Anderson. She has released six albums, three compilation albums, one live album and two albums with the group, Bryndle.

Taylor’s Billboard chart hits include “I Will Be In Love With You,” “First Time Love” and “I’ll Come Running.” He has released more than 20 albums. Two of his songs were covered by his brother James Taylor. He has been a faculty member at Berklee College of Music since 1989.

In March 2019, the American Public Television special “Livingston Taylor Live from Sellersville: Songs and Stories,” recorded at the Sellersville Theater, Bucks County, began broadcasting on PBS stations.

Taylor has performed concerts in the Lehigh Valley a number of times. He has had multiple Musikfest appearances, was at the Allentown Fairgrounds in 1975, and played Southside Bethlehem’s Godfrey Daniels club 14 times from 1985 to 2005. He was previously at the Musikfest Cafe in 2014.

Bonoff plans to tour this spring, accompanied by guitarist Nina Gerber.

Taylor says he will “go back into the studio in the new year, assemble a fresh bunch of songs, and try to put them into a digital configuration.”
