The Raise Your Voice concert kicks off from 2.30pm on Saturday and will feature local favourites including The Convicts, Groove Factorie and Social Hand Grenade.

The concert's special guest Adam Thompson of Chocolate Starfish will headline the event.

Musician Daryl Day, who has been involved in organising the concert, said the response from bands was "instant."

"To be able to express yourself for a good cause like this is gratifying," he said.

Mr Day said the opportunity to play to a larger crowd with quality production values was a major drawcard for bands usually found at local pubs.

"And the audience gets all the scope of local acts at the same time," he said.

Wagga band Bitter Shoosh will be performing a song written by Scott Cochrane to recognise the efforts of Australian firefighters over recent months.

The cause hits close to home for many of the musicians who come from towns hit by this summer's bushfires, including Adam and Scott Urquhart of Social Hand Grenade.

The brothers hail from Adelong, with former firefighter Adam returning to help protect his parents' home as fires threatened the town at the start of the year.

Mr Day thanked those involved with the quick organisation of a concert he said would normally require six to 12 months' preparation and acknowledged the support of the Wagga Show Society for providing the large venue.
