Pearl Jam answered Taylor's request after receiving a heartfelt letter asking for help to raise money by putting paint on canvas.

Taylor's brother Mitchell, 7, died 18 months ago, having been one of just 500 people in the world diagnosed with the devastating Niemann-Pick type C, a terminal disease for which there is no known cure.

Sufferers gradually forget everything, including how to walk, talk, eat and breathe.

There will be a public exhibition of the paintings at South Melbourne's Smart Artz Gallery from March 1-8.

They will be auctioned on eBay from March 3-12.
