I'm not really sure where you were going with this, but... I think it would be better if it was waves instead of a vertex (can't remember that v word). Text is hard to read. You could try a clipping mask (provided you know how to do that). IMO there's too many black random things sitting around there. Other than that I like the rainbow colors and stuff.
Why does nobody here think I know what a clipping mask is? And why can nobody ever tell that I'm using them? Lol. Anyway, the text is meant to be difficult to read. It draws true fans into the art... Think of it like the lyrics to a Nirvana song. EDIT: I think you might be right about repeating radial gradients rather than a spiral, though.
