Sound Design project <- feedback please!

[Andrew Robinson]

Part of my university course is a module in Creative Sound Design. For
this, I have to make an audio file between 4:30 and 5:30 long, that
explores recording technology. I was instructed to stay away from
'things I would usually do', (no glitchy instrumental music) and where
possible make sounds myself rather than use sample libraries.

The result is a humorous (I hope!) documentary on the history of sound
recording, which you can hear at:

Any feedback on mistakes, wrongly set levels/eq/panning etc., any
things that could do with a tweak, etc. would be much appreciated.

To give you some idea of what to expect, it's starts with a field
recording from the museum of mechanical sound, it includes 3 cover
versions, some with vocals by me (just in case you've ever wondered
why I only do instrumentals), and an acid/dubstep 80s classic. The
bits that didn't make the final cut include a psychedelic sitar cover
of Chic's good times, a section recorded in a (fake) underground cave,
and me doing Robbie the Robot impressions using a mic down a long
cardboard tube.
