He said 10 musicians from Rainbow district took part in the first event.
“Friday night’s event helped to introduce a lot of talented musicians who hadn’t met before,” he said.
“Most people I spoke to after the event said they were really keen to make it a regular thing.”
Musicians ranging from guitarists, bassists, drummers and vocalists took part in the session.
Mr Gosling said plans were to encourage more people from across the Wimmera and southern Mallee to take part.
“The plan is to branch out and use each session as a means to promote the event, with filming the sessions and taking photos,” he said.
“I think reaching out to anyone within a 45-minute radius of Rainbow, such as Warracknabeal, Dimboola, Nhill and Hopetoun, would be a good start.”
Mr Gosling said he was hoping the event would provide more opportunities for musicians to collaborate.
“Opportunities to play music in town have been limited in the past couple of years,” he said.
“Not everyone wants to perform on a stage in front of a crowd – so this is a good, relaxed way of getting people involved and improving people’s playing.
“And it’s as much about socialising between songs as it is playing the music.”
Mr Gosling said plans were to encourage school-aged students to participate, to encourage younger generations into music.
