Ghost in the shell - original blues

Dear all

I've just made a song in which I moan about work and would welcome feedback: http://www.youtube.com/watch?v=fNHTFLTdAIg

I tried giving it a raw feel with just one guitar track, one voice/harmonica track and one percussion track. I also had a go at singing in a higher register than usual following feedback on earlier attempts. Please offer your frank opinions on whether these developments work and where to concentrate my efforts next.

If you would like me to comment on one of your songs, then please point me towards the relevant post.

Cheers

Phil
