They have all recorded singles with producer/engineer Nat Love.

Cassidy-Rae's debut single Be Strong was released on Friday on David Simon's label Oxygen Music Group, and has already had airplay on Radio 2RDJ FM.

"Cassidy-Rae is one of the most brilliant singer-songwriters, who comes in every week with five new songs — none to throw away," Mr Simon said of the pianist from Glenhaven, who came under his notice a year-and-a-half ago while she was still a student at Rouse Hill Anglican College.

"She attended a seminar of ours, and I asked her to send through some of her demos.

"Be Strong touches on the death of a good friend of hers [Daniella Meads-Barlow] and issues around bullying growing up.

"It has quite a powerful video that shows her walking through a school yard, and different bullying events happening on that walkthrough."

Cassidy-Rae said: "I was 15 when Daniella died from the 'dead-in-bed' syndrome, a hypoglycemic coma caused by type 1 diabetes.

"Be Strong is as much for her as it is an anthem, raising awareness for anti-bullying; acknowledging pain, encouraging strength, and moving on."

Its release has led to an outpouring of bullying stories, from friends and strangers.

"People seem to be really connecting with this song and reaching out, which is wonderful," Cassidy-Rae said with reference to the growing number of emails and Facebook posts she is getting about her song, which she described as organic pop.

"I've had people telling me 'thank you' for writing this song."

Mr Simon said about 350 people attended the single's launch party at The Factory Theatre, Marrickville, on Friday night.
