"Bands like Kora started off in metal, and Tiki Taane cut his teeth in metal, so it's open to everyone.
"We've had a jazz band and a rockabilly band, and even my own band were asking if we could enter."
Wegman said four bands would be selected each week and featured on Sound Valley's social media pages, with voting based on how many the times the bands were tagged, mentioned and liked.
"There'll be four bands competing each week for four weeks, with one winner at the end of it all."
Wegman said submissions should be for original music only.
"I respect what covers bands do, but in this case it's about finding an original artist and supporting an original artist.
"It's for a band to open the show at the start of the day and play for half an hour or so.
"It's important that bands submit some of their recordings or links to a stream, as well as things like bios and electronic press kits."
The first round of the competition starts on Monday, July 6, with the winner being announced on Friday, July 12.
