Factoring in a) a short Broadway run b) many complaints from critics and public that the score was empty and c) the high cost of making a cast album with little hope of it ever breaking even I would guess that if it hasn't happened by now, it won't be happening.
Cast albums are expensive. Even now when they no longer have to pay the cast a week's salary they still have to be paid for the sessions, the orchestrations have to be paid for (again), any photos they use in the packaging have to be paid for, plus studio time, mixing and mastering, marketing.,..it all adds up and at best the CD might sell 1,000 copies. They would have to charge $500 a Cd to break even.
I understand your obsession with getting a CD of every show, Bryan. But it just isn't possible with these kinds of economics. If you win the lottery you can set up your own label and record all these flop shows. If you do, I will buy one, but I think you will be shocked at the pathetically small number of copies some of these recordings actually sell. .
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
I host a weekly one-hour radio program featuring cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com
