Sydney pop chanteuse Sarah Blasko will play a special show alongside the WA Symphony Orchestra at Kings Park on February 23.

Tickets go on sale on October 26 - the same day the ARIA Award-winner unveils her fourth studio album, I Awake, a sumptuous collection of intimate yet ambitious songs recorded in Stockholm, Sweden and Sofia, Bulgaria, with the Bulgarian Symphony Orchestra.

Blasko handled production duties on I Awake, which follows three platinum-selling albums, the most recent being 2009's brilliant As Day Follows Night.
