I cast "Baconstorm!"
Maybe use an ability check to keep it up, like holding one's breath or other such taxing activities.
For example, make the bard make an escalating CON check every minute, +1 every check: so DC 10, then DC12, then DC14... The DC decreases by -1 for every 10 minutes of resting not playing music, and is completely reset with a night's rest.
If he ever fails a check, his voice if gone for the day: no more music, no spells with verbal components, no witty banter, etc. He regains his voice the next day.
Also, I assume the others in the party are suffering penalties to their Listening checks...?
