I would say it is raw, produced, fabricated, and felt.
When a band is jamming, or a song writer is writing - it is a raw "flow." When something sounds good, or feels right there is an ah ha moment where that flow becomes a song. That song is then replicated again and again. This feel can be re-captured with live concerts.
Then that band goes into a studio and cleans up the raw song with a producer. The guitar is too loud, the singer should be hitting a higher note, the drums are not crisp; whatever is "wrong" is cleaned up. Modern studios can manipulate everything to give a clean sound. There are artists like Lenny Kravitz that sing and play all the instruments on the same song, or Dave Matthews who use multiple overlapping guitar tracks on studio records.

Producing isn't a bad word. Think of the "raw" as the sketch and the producer is doing the detail work on a painting. They are collectively working together to make something that sounds great.
The studio then wants to make money so they fabricate a sellable product. They add artwork, put it in a pretty box, make posters, send the artist on the late-night show circuit, Morning Shows, radio promotion, yadda yadda. The artist is also fabricated - they now have a stylist / PR person / choreographer / chef / personal trainer to create the illusion they desire to maximize sales of CD's, merchandise and concerts. Different bands are affected by this more than others. There are some "artists" that stay mostly in this category. Think Brittany Spears / Boy Bands. They are for the most part the product - not the music.
Good music is felt by everyone along the way.
