MYOCUM opera singer Lecia Robertson has put down the head of John The Baptist and jumped into Barbie's shoes for the upcoming performance What's that Spell at the Bangalow Music Festival this Saturday.
Last year, the Northern Rivers performer was in Adelaide singing to a severed head in the title role of Richard Strauss' Salome.
In a role that couldn't be any more of a contrast, Ms Robertson will belt out a pop cantata in a Barbie costume as part of The Odd Couple concert.
Ms Robertson said it was a big change from the extremely serious opera Salome.
"A year ago I was doing probably the hardest opera I've ever had to learn by Richard Strauss who writes the hardest music in the world," she said.
"And (I played) this bizarre character who orders the head of John the Baptist and then sings a whole 20 minutes scene with the head, at one point loving it, at one point hating it.
"It's really very, very different to Barbie. Salome is a very complex character and Barbie is two dimensional."
During her stay in South Australia, Ms Robertson also stepped into the soprano lead in Verdi's La Forza del Destino halfway through opening night when the singer she was covering became ill.
With great reviews for the opening night, she went on to finish the run.
Ms Robertson's theatre career began when she left school. At age 22, she travelled to London to be in a West End musical.
After 17 years training and performing in plays and operas, Ms Robertson made the move back to the Northern Rivers
In her 15 year professional opera career, Ms Roberston has sung in English, French, German, Italian, Russian, Czech and Spanish.
Ms Robertson said the cantata would come in five movements.
"It's quite funky," she said. "It's not operatic."
