The members of Sonia Dada, like its music, are not easily grouped into a specific category.

“The musicians are pretty diverse and versatile,” bassist Erik Scott said from the basement of People’s Bar and Grill Sunday evening. “We’re not slaves to style. We like to serve the song more than with any particular style.”

This comes through on both Sonia Dada’s studio releases, which span almost all contemporary musical genres from techno to gospel.

However, according to Scott, this eclectic style is not premeditated.

“There’s some folk, there’s some jazz, a lot of R&B with some rock,” he said. “When we record songs for the record, and even live, we sometimes take different shapes just because we can.

“We don’t try to mold the song into a style,” Scott added. “And frankly, we like the diversity.”

Scott feels this diversity is what makes Sonia Dada so interesting, especially on their albums.

“You might have heard a song on the radio, so you buy the record and take it home, and there was 10 tracks of the same song,” Scott said.

“With us, it’s more. You hear diversity — it goes from one thing to another.”

With this 10-date tour, starting in Indianapolis and wrapping up at The Great American Music Hall in San Francisco, a few additions will added to Sonia Dada’s diverse nature.

Since singer Sam Hogan has been having difficulty with a drug addiction, Shawn Christopher will be adding a female flavor to Sonia Dada’s usual all-male line-up.

Christopher will be singing the third harmony which Hogan usually takes, along with vocalists Michael Scott and Paris Delane.

Christopher has had experience with Sonia Dada in the past, singing background vocals on both studio albums.

Although Christopher will record on Sonia Dada’s third record, the band is uncertain about the status of the new line-up.

“She’s singing really well,” Scott said. “It’s hard to tell what will happen. Whether it will be a permanent thing or not, I can’t say at this time.”

Also bowing out for this tour is percussionist Hank Guaglianone, who is currently undergoing therapy for tendinitis. Larry Beers, a friend of the band from its hometown, is sitting in his place.

Guaglianone is expected to return to the band to record its third album due out early next year.

For now, however, Sonia Dada is trying to accomplish one thing: great music.

“It would be wonderful to have timeless, great music,” Scott said. “Something that has real musicians who can play, real singers who can sing, doing real songs that are really good and not just novelty songs. And that’s what we want to do.”

Although last night’s performance was sold out, there are tickets still available for tonight’s performance for $15. Showtime is at 9 p.m. with Vigilantes of Love opening.
