Why do singers always bring live bands without accompaniment to their solo concerts? Why?

Nowadays, many people will go to their idol's concert. Usually, when a singer gives a concert, he will sing with a live band instead of accompaniment. Let's talk about why singers always bring live bands without accompaniment when they hold solo concerts.

First of all, this is to respect the fans and play all the things of the singer with a live band, instead of playing a few perfunctory songs with accompaniment.

Secondly, this is actually the need of live performance. Imagine if you were the only one singing on the stage, it would be too empty and the live performance would be really embarrassing. Another function of playing with a live band is to make the music more shocking. The sound of beating gongs and drums at the scene is very emotional. This kind of live singing can drive the audience's emotions and better play the layered sense of the song. Sometimes the singer will interact with the drummer and guitarist of the band, so that the singer looks natural and the audience looks comfortable. The melody played by the live band may fluctuate, instead of always being dull in the same tune like accompaniment, which will greatly change the feeling of the original song, give the audience a brand-new feeling and enjoy it.

In short, personal concerts always have live band performances, which is a shock that many people can't do when listening to mobile phones and mp3 players. Why else do many people want to go to the concert even if they spend so much money? It must be that the live performance can give the audience a shocking feeling, so that the audience can enjoy the ultimate music, not as boring as listening to mobile phones.
