"Fat Freddy's are only doing two concerts this summer and we're one of them. They don't play a lot and their stage shows are never the same. They play for a couple of hours so you get great value."
The concert is promising to be a fusion of soul, reggae and funk.
Ms Sanders originally announced three bands - funk remix masters Hipstamatics, a 10-piece band, and Meta & The Cornerstones.
She has since added Strangely Arousing, who open the concert at 4.10pm, The Boom Cat and Manalion to the concert.
Hipstamatics play arrangements and remixes of well-known songs in their funky way and are guaranteed to get you dancing, Ms Sanders says.
African artist Meta & the Cornerstones fuse reggae with Afro-pop, hip hop, rock and soul. They have been described by National Geographic as the future of reggae music and are picking up fans all over the world.
Ms Sanders said she wanted music fans to grab a camp chair or picnic blanket and have fun. "Enjoy some great music, have a good dance and enjoy the New Year."
Food and drink is available. A liquor ban is in place.
