This passage by Zhang Wei is actually very long. The general meaning is that rock musicians really shouldn't pretend too much, because if they pretend too much, they will suffer a lot and can't eat, because mouth is their original sin. In fact, this is to persuade Xiao Le, the lead singer of penicillin, to be an experienced person. Never treat the world casually, but be in awe.
Of course, awe is not to please the audience, but to live a high posture and live the truest self. In fact, the lead singer of penicillin is really a pretentious person, because at that time he said that britpop only existed on that small island, and they were a group of Chinese rockers.
In fact, they just don't want to admit that they are imitating, although they are really imitating other people's gestures. So in fact, Zhang Wei's attitude is not wrong. He is really a very punk. He suffered such losses when he was young, which led to the popularity of such stalks in Beijing. People who have never played Zhang Wei in Beijing have lived in vain, which shows how much Zhang Wei can offend people and pretend when he is young.
So now he is actually summing up the experience and lessons at that time and telling these precious experiences to Xiaole. This is really a kind of love for the younger generation. Don't let the editor mislead us and let us misunderstand Zhang Wei. Maybe the whole world will owe Zhang Wei an apology.
