These 50 or so zebra finches are singing their hearts out alongside loads of different musical instruments, like guitars and cymbals.
It's all part of an exhibition at an art gallery in London.
The artist used to be a composer but he got bored of creating music by writing notes on a page, so he decided to do something a bit different.
The exhibition is open for two months and the birds will be recorded.
There are no plans for a single release yet though... Hayley's got the story.
