What do they do?
To put it simply, they make the songs you love sound good.
They choose and place microphones. They suggest musical ideas. They add effects like reverb, delay, chorus. They mix all of the instruments and vocals that were recorded on separate tracks into the final stereo (sometimes mono) mix that you play in your car or rock out to on your Iphone/IPod, etc...
They are the "knob Twiddlers". (I know, sounds like a dirty metaphor...)..
...Read the album credits and liner notes, you'll learn alot!
Peter Coleman started as an engineer for the great producer Mike Chapman and then went on to produce artists himself. If you aren't into 80's AOR/melodic rock or new wave you might not like his work, lol test drive a few and see if you like....
