Hi Zelig,
wow, that was an experience rather than a listen, I haven't felt tension like that in a song in a long time. It reminded me of an improvised performance rather than a recording but that is a good thing because it sounded as if the the song wrote itself, if you know what I mean. I'm not sure if polishing it up would enhance the song or take something away from it, I think I would leave it if it was me but Andy (the other half of TNMC) wouldn't, so at the end of the day its like all things musical, down to personal taste.
As for the lyrics, they were the right side of ambiguous, enough to keep in tune with the ambiguous music but they made enough sense that they didn't seem odd.
Overall I liked it, you didn't know where it was going and I like that.
Liam.
