Hey, all!
I am a hobby photographer and my fiance is a professional journalist; we collaborate frequently for music festivals and concerts; I take photos of as many bands as I possibly can, while she likes to record interviews with members from the bands in the media tent area.
She is leaving her television news job. We previously were able to use their large, fancy cameras, and professional-level microphones to conduct interviews; not anymore. 
That all said, I am looking for an economical, decent-performance setup to perform interviews with bands, while at these events. I currently own a D3400 and a D750, and am not opposed to bringing my laptop to these events if you have recommendations for a good setup centered around a Windows PC. 
In my mind, I envision using one of the DSLRs (preferably the D3400), or maybe a webcam on the PC, with two separate microphones (one for her and one for a band member), and potentially headphones, so they can tune out the surrounding noise from the concert/festival, and focus on the interview.
Anybody have some tips or suggestions?
Thank you for reading, and thanks in advance for any advice you can offer. 
V/r,
Garrett
