My go-to examples of people going from skeptical to "WTF?" are Waka Flocka Flame:

He also seems to be able to 'find' people just before they really make it big/mainstream, like Kendrick Lamer, Billie Eilish, and Tyler the Creator. I heard about them from Narduar before anywhere else.

Will check him out, thanks for the tip!

His researching skills are indeed impressive, but I feel like he's a bit "loud" in his personality/character and that can take some attention away from the interviewee.

I'd say he's just eccentric, and takes a bit of getting used to in terms of style. also, IIRC, this interview got him some REALLY big ones (including Jay-Z, I think) because Pharrell told everyone he knew to that they had to talk with Nardwuar.

At the very least in terms of doing proper research on a subject, I think there's no one better.

In his interviews he really doesn't draw attention away from the interviewee. You're right about him having a strong personality but it's obvious to me that he tries very hard to never outshine the person he's interviewing.

If you're not used to him, and are coming in 'cold' to watch one of his interviews, then it can be a bit distracting. After a few I think it goes into the background more.
