I found this blog very interesting. Some points that stood out to me:
Recorded music revenue is down 64% since 1999.
Per capita spending on music is 47% lower than it was in 1973!!
The number of professional musicians has fallen 25% since 2000.
The average income of a musician that files taxes is something like 35k a year w/o benefits.
Of the 75,000 albums released in 2010 only 2,000 sold more than 5,000 copies. Only 1,000 sold more than 10,000 copies. Without going into details, 10,000 albums is about the point where independent artists begin to go into the black on professional album production, marketing and promotion.
