The music biz. I am glad to say is changing with digital technology. It puts more money back into the musicians, prob. even more than indie record labels. One could record, post it, and sell it. No record label BS.
The million dollar record deal is a bit of a bogus idea that money is made by the musician. A typical well managed deal in the 70's or 80s might see the artist get 10 points of a record. Worse if the artist, is a 5 piece band. Each member, assuming equal division gets 2 points each.....
About 50 points goes to the label. The other points go to all the advances, studio time, production costs, copyrights, accountants, legal fees, and so forth. Then you have tour and promotion costs which need to be recouped and if the sales don't pick up, then haha. Somebody somewhere picks up the tab for rock and roll excesses, and all the TVs flying out of windows....
Unscrupulous business practices are better policed now with better knowledge about the biz. but still there are people looking for that million dollar deal.
FYI: a hit pop record in the UK is something in the region of 150 000 units. Not a lot, but these are the figures. Of course there are those that would sell in excess of this figure.
A mediocre (sales) fusion recording might sell 15000 in its first year.
Say a record is £10.That's 150 000 quid. 10% is 15K. 4 members in Brand X, --- that's about under £4K. That's a month's salary for many. That's what you get paid, i.e. if some one kept the books tidy....This of course is simple accounting, in reality the sales are in dribs and drabs and you might get your 2.5% royalty for 1000 units that sold last year. In simple accounting terms that's roughly £250.
You'd get a bit more if you own the copyrights of the tunes.
My days in the music production biz are over, and I play now in various cover bands and I have a full time day job and career. How much do I make gigging annually playing silly covers? About 40 - 50 gigs a year, each gig roughly about £100. Yeah, about 4K.
