Edging closer to greyness

Shades of Grey (and other short stories) is well on it's way. I have 4 finished songs and I want to have 6 on the EP I think, maybe 7, but it's getting there at least. This might sound pretentious and arty, but I need to find a direction for the EP, a common theme which links all the songs. I think that's what I enjoyed about the first EP, the songs sort of followed on from each other, and I want to do that again. I think I need to get some ambient noise from somewhere!
