Cover art for The Garden lyrics by Einstürzende Neubauten

I think this is Blixa's the carny (In which Nick Cave doesn't dig down the horse named sorrow deep enough, and the rain (tears, sorrow) makes sorrow appear again...rising from her grave "We shoulda dugga deepa one").

It's a song about sorrow, a woman has left him but she can find him again in the garden if she wants. Unless it is raining...meaning he is weeping then she won't find him, he is elsewhere. The scream of course is there for the pain, and the music progresses very slowly forward...he is dealing with it but it doesn't go in a fast pace.

Or maybe it is enough to say that the song is like so many others are simply Rorschach tests.
