The ever-mysterious, multi-talented Sia is renowned for breaking boundaries and maintaining her individuality in an image-obsessed industry. Revered for her wide-ranging vocals, from Giorgio Moroder’s “Déjà vu” to “Fire Meet Gasoline” to “Elastic Heart” to “Big Girls Cry”, Sia has constantly proven her ability to provide a strong power ballad.

Now, Sia has lent her hand for a cover of The Mamas and the Papas’ “California Dreamin”, the folk rock classic from the 1960s. The track will grace the soundtrack of the forthcoming blockbuster San Andreas, headed by Dwayne “The Rock” Johnson.

Sia’s take on “California Dreamin”, once again proves her resolute power ballad ability with this stirring track. With its slow-burning choral and orchestral opening, Sia recreates “California Dreamin” into a track that is effective, emotive and haunting. Listen below.
