Premium Content Subscriber only The line-up for the Agnes Blues, Roots and Rock Festival keeps growing with another artist added to the line-up. New South Wales artist Karl S Williams will perform at the main Marquee Stage in February. From the cane country of northern NSW, Karl has built his reputation over many years playing around south east Queensland venues. Karl has toured various Australian festivals such as Bluesfest, Woodford Folk Festival, Dark Mofo, Panama, Queenscliff and Festival of The Sun. Karl's songs are a distillation of life, love and the human condition. His sound is a combination of folk, soul, and blues -with a weaponised voice that can soar with the best of them.
