flop musical (noun):
a musical which fails to achieve commercial success due to low ticket sales, bad press, or simply being ahead of its time.
Flop! Hit Songs From Musical Misfires is a weekly radio show for musical theatre lovers to celebrate Broadway and West End Flop Musicals.
What began as a 10 minute (really, 12 minute...then 15 minute...then 18 minute...) segment on The Passion Project with Kate McKeown back in May became a 30 minute show in July. And now, Flop! is a full-length hour-long radio show, streaming live every week on Fridays on Quarantine FM!
