I think WILDsound is an outstanding festival. To have your work read aloud and showcased on the internet is amazing! And the folks who run the festival are super cool. I had a very full plate at one point this year, and they were very patient and encouraging with my rewrite submission.
I came across the WILDsound Festival after I completed my Spec and received positive feedback from those I trusted to read it critically. I decided that it was time to take my writing more seriously, and WILDsound had tremendous reviews when it came to acquiring an agent/manager.
