Grab your sweetheart – and a pair of concert tickets – for Valentine’s Day, as Grammy-nominated blues and gospel artist Ruthie Foster is set to play at the Zeiterion Theatre this Friday, Feb. 15, with Grammy Award-winner and Rock and Roll Hall of Fame inductee Mavis Staples.

Foster, who attended Sunday’s 55th Grammy Award celebration in Los Angeles, CA, said the nomination was “a nice surprise.”

“It’s validating more than anything,” said Foster. Her 2012 recording, Let It Burn, was up for Best Blues Album.

On Dec. 5, the day the nominees were released, Foster was spending time with family in her hometown of Gause, Texas, a small town just north of Austin. Later that night, her manager called her to share the good news.

“I spent the day with my sister and brother just getting back to my roots and then I got that call,” Foster said. “It was pretty cool. It all came together full circle.”

Foster also talked about something else that excites her: the fact that Staples will be joining her for the show.

“I love her to pieces,” said Foster, noting that she channeled Staples when recording a few songs for Let It Burn. “I brought her sound into a couple tunes, mainly the Los Lobos song, because it’s in a register I don’t sing in much.”

With the exception of two songs, Let It Burn consists of 11 soulful covers, including “This Time,” by Los Lobos, as well as Johnny Cash’s “Ring of Fire,” Adele’s “Set Fire to the Rain,” John Martyn’s “Don’t Want to Know,” plus hits by The Band, Pete Seeger, Crosby, Stills & Nash and more.

She recorded it in New Orleans with producer John Chelew, another Grammy-Award winner, who suggested Foster cover these particular songs.

“He brought a lot of new tunes to me from different genres for this album that I hadn’t really got into until then,” Foster said. “I wasn’t familiar with John Martyn until I did this album and now I’m a fanatic for his stuff. I just can’t find enough of it. I’m chasing everything he’s got. It’s sad he’s no longer here.”

The CD features an array of artists, such as The Blind Boys of Alabama, soul legend William Bell and the rhythm section of The Funky Meters.

It also includes New Orleans-bred guitarist Dave Easley, renowned saxophonist James Rivers and Ike Stubblefield on organ.

Foster said The Blind Boys brought a lot of “earthiness,” as well as a “spiritual side” to the recording. Growing up with a group of uncles who all sang, she said hearing them brought her back to her childhood.

“They were real close to that sound I was so familiar with, so having the chance to put it on one of my albums was just a huge opportunity,” said Foster. “I wasn’t sure what the songs really meant until these guys started singing on them. They really just made the song ‘Welcome Home’ shine.”

For the first time in her recording career, Foster, who plays multiple instruments, including piano and guitar, didn’t play an instrument on Let It Burn. It gave her a chance to hone in on being a singer and get the chance to “channel” a variety of singers.

“It was different and very welcoming,” she said, adding that the recording process of the entire album was a pleasure. “Getting someone like George Porter, Jr. (of The Funky Meters) to be the first to say ‘yes’ to being a part of a group of guys that were going to lay down the tracks. Then, everybody else jumped on board. It was huge. My manager happens to be the manager to The Blind Boys, so all he had to do was make a phone call. We made it happen. It really came together well. I’m really happy with the way it turned out.”

The Grammy-nomination marks her second, as The Truth According to Ruthie Foster was in the running for Best Contemporary Blues Album a few years ago. She also has a long list of nominations and awards, including three consecutive wins for the Blues Music Award in 2010, 2011 and 2012.

“All of them are special,” she said. “I have three Blues Awards, but it means something different each time.”

This year, she hopes to hit the studio again. Writing more and recording with Keb’ Mo’, a three-time American Grammy-Award winning blues musician, is a possibility.

In terms of her show at The Z next month, she plans on bringing a full band with her, as she will playing a lot of songs from the CD.

“It should be a good time,” she said. “I like getting the chance to be introduced to the audience. That’s what’s great about what I do.”
