When each live performance signal is transferred from one live performance
providing apparatus to the next, with the live performance providing
apparatuses having the respective connection orders thereof, the live
performance signal is mixed with a live performance signal captured by
the one apparatus. The end (n-th) live performance providing apparatus
mixes a live performance signal captured by itself with the live
performance signals mixed by all prior live performance apparatuses,
thereby finally providing a complete live performance signal as a concert
sound.
