The Royal Whanganui Opera House stage has the capacity for large groups of performers or in this instance a group of musicians and an audience.
Whanganui Artists Open Studios have collaborated with Brass Whanganui for Sound Canvas - a multi-sensory experience where the audience will take centre stage.
A maximum of 120 people will be seated on the stage where they will be surrounded by projections of works by Whanganui visual artists while listening to music played by 32 brass players.
"The audience will hear what I hear," says Brass Whanganui musical director Bruce Jellyman.
"The music happens around them and there will be singing, theatre and poetry readings as well."
