Like a DJ doing beat matching! Not the most effective way to turn on
an audience ;-)

Inviting the audience to take part in the the full music/sound
creation process may sometimes win your more fans than providing an
audio presentation of the music that sounds perfect from the first
second till the coda.

That's a very good thing. With my
all-acoustic-bleeding-into-the-sound-field method I'm wearing custom
moulded minus 15 dB silicon in-ear plugs. They block volume but keep a
fairly correct frequency respons. And they are soft to prevent a
deafening glitch to open if you should sing or take a zip of a drink.

Ouch! A related product I heard about is these covering cans that also
have microphones on the outside. They are adding a phase inverted tiny
signal of the outer world to the music you are listening to and since
this happens only for one ear the outer noise is then being phase
cancelled.
