Organiser Danny 'Brotha D' Leaosavai'i told 531pi the response from the musicians had been heart-warming.
"They're all donating their time and their talents for this.
"The monetary value of each of these artists is far beyond what probably we could have paid for...I'm speechless. I want to thank them personally and sincerely."
Brotha D said the lineups might differ at each venue but more details could be found on the event Facebook pages.
