Macquarie Corrections officer Anthony Ferret has been able to use his skills as a trained audio engineer to help inmates express their creativity, increase skills and ultimately build confidence for when they're released from prison.
Mr Ferret said most inmates were quite musical, and as most people would know listening to it is a relaxing experience and escape from day-to-day life.
He said working with inmates to write and record music helps them work toward becoming the best version of themselves.

"I can't speak for other prisons, but from where I've worked there's nothing like this at another jail," he said.
"We're very privileged with the Macquarie model, that we're able to do something like this.
"The inmates are very appreciative of it as well, getting the chance be open in their expression."
Mr Ferret said he encourages a high level of professionalism with the inmates when creating music, which in turn helps instil those characteristics into their personal attitude and behaviour throughout their day-to-day interactions.
"You think professionally, you therefore will act professionally," he said.
"It doesn't mean you have to be the best, but you give it your best and it's no different when working with the guys in here I say, 'you're coming in here, were not mucking around this is serious."
"It's an art form and it's supposed to be fun, but you put your craft into it as well, and I find that attitude then correlates to their personal attitude as well."
"That professional attitude comes from a professional mindset ... the same thing goes here [in the studio] and for their day-today life in the jail.
Mr Ferret has also helped pull together an inmate band, the Green Mile Express who have recorded a number of original songs.
The band play a mix of hip-hop, rock, reggae, soul, and folk and is made up of six inmates including three guitarists, a drummer, singer and back-up vocalist, which Mr Ferrett said each bring something unique to the sessions.
"We've been privileged to receive some recording equipment ... and we've been able to use that to start recording music, and we actually recorded a Christmas carol album that we bought out before Christmas, and we also have an album with 11 original songs all done by inmates here, which is pretty incredible," Mr Ferrett said.
"It's a pretty cool little project."
