Reviews don't seem to count for much any more.
BYE BYE BIRDIE gets predominantly negative reviews and has been selling close to capacity. FINIAN'S RAINBOW and RAGTIME got terrific notices and are struggling to build their audiences.
Even so, as mentioned GOD OF CARNAGE is still making a healthy gross and the cast were promoting it on the CBS telecast of the parade.
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
