How to Shoot Songs in RAW

I just wanted to have the best gear I could have so I wouldn't outgrow it. As far as settings, what I started with was the first few shows, I started in aperture mode. Aperture is going to be like what's going to be focus versus blurry depth of field. So if it's, you know, for me, I shoot normally in 2.8 and just leave it open. You can dial it in and go like 7.1. And how many photos do you usually shoot in the three songs? It depends on the artist or because I'm using two cameras at the same time. Usually 2470 will be full band, 7200 will be individual band
