Recommendations for recording concerts online

Hello, this is my first post here, I am a young man passionate about music and it was in my forties where I got into the world of bootlegs, I have seen that Editors will have several presentations at festivals, and I want to ask for some recommendations to record concerts, what can I do to make my recording look good, I use the windows factory recorder and sometimes the OBS although I do not like it very much because the sound is spliced.
