As well as making SL art, I've been experimenting with the creation of sounds and soundscapes. I have limited skill and use free software but I hope my enthusiasm makes up for these deficits. Some of these sounds I upload to SL to add to my artworks. Most of the sounds I use are from Freesound.org - a fantastic site and well worth checking out. You'll find all the Freesounder's credits on the linked pages.
Festival of Colour
Here's a link to one of my latest soundscapes, Festival of Colour.
Remember is a scary soundscape about a woman who is forced to recall key incidences of her life at the moment she dies. She was far from perfect and there are consequences!
