There's legit nothing wrong with this. He's singing his ass off. You weren't there, so you can't know what the audio was like if you weren't there. Phone quality videos don't do shit to determine quality.
I dont understand what you can expect? This is as far as I know the first gig ever and its a pretty big thing opening for A7X. I think it sounds great. As with everything, experience will make a huge difference. For a starting point this is pretty amazing
