Mandy Moore was so nervous about premiering the tunes from her upcoming album at an intimate Los Angeles club that she sought help from a hypnotist.

The trick seemed to work, although the former teen idol did not take it to the next logical step and munch on an onion or remove any clothing.

“It is the most bizarre situation you can imagine,” a clearly relaxed Moore recounted at the beginning of her show on Saturday. “It’s almost like therapy.”

Music fans might have found the show bizarre — in a good way. The one-time Britney Spears wannabe took to the stage at the 280-seat Largo at the Coronet theater accompanied by a rootsy band that included a pedal-steel player. A string quartet also appeared.

That’s quite a step up from the days when the comely starlet cooed “Candy” with a menagerie of background dancers. But while Spears is still stuck in that role, Moore has moved on to the realm of Gram Parsons and Lucinda Williams.

The 25-year old singer, who married rocker Ryan Adams last month, unveiled most of the tunes from her sixth album “Amanda Leigh,” which is due in stores on May 26. She co-wrote all the songs, working mostly with indie musician Mike Viola, who played guitar at her show.

Upbeat tunes like the Fiona Apple-inspired “Fern Dell” and the infectious “I Could Break Your Heart Any Day of the Week” shared the spotlight with more introspective fare such as “Merrimack River.”

Moore, an unabashed fan of Paul McCartney’s second solo album “Ram,” paid homage to his other band Wings by covering “Let Me Roll It.” She also sated nostalgists in the surprisingly diverse crowd with an overhauled version of “Candy.”
