Both acts have been added to the bush festival, which takes place just outside of Sydney in December.
Format B and Alex Smoke have been added to the line-up for December's three-day Subsonic Festival.
It was announced earlier this month that both Format B and Alex Smoke would be in Australia for The Likes Of You series, which is occuring in both Sydney and Melbourne. Now, it transpires that punters have the option of catching both acts away from the traditional club environment, two-and-a-half hours north of Sydney at Riverwood Downs Mountain Valley resort. The resort features an array of amenities, and describes itself as a "luxury camping experience". Format B and Alex Smoke will join Jamie Jones, Tom Clark and Salmonella Dub as the festival's headliners.
