For musicians, Rick Beato and Nardwuar the Human Serviette. Nardwuar’s preparatory research is always very deep, and musicians have repeatedly praised him for asking interesting questions outside the repetitive and superficial interviews they normally have to give when promoting a new album or tour. Since Beato made a career on YouTube where he doesn’t have to keep things as accessible to a general public as in legacy media, his interviews can get deeper into technical matters of music-making.
Nardwuar is interesting because he's a litmus test: some people just absolutely don't like him and his persona and his schtick, and the fact that he's clearly done more thorough research than any other interviewer they'll ever talk to doesn't move them. And then other people appreciate right away how unique he is.
It's funny that many of the punk rock types don't like a guy who is as DIY as Nardwuar.
