While recording, we already take the decision if we will edit or not. The first was a folk song, very rhythmic and it was easy to be a little exited and rushed the performance. For this song we decide to make edition, to be sure everything is tight.
The second was a very intimate song and it was like a cry from the heart. The recording was with the full band and they were just playing with their heart and soul. The band was pretty tight and we had a great vibe around it, this is one reason why we can keep the performance. The singer was very great and we can keep the track of his vocal, not a lot of bleed on it so we already had the perfect feel.
There is no great or wrong answer about editing, simply do what you are comfortable with. For me, I always go with the song, some songs will be more apt to be edited and some others you just want to keep it as a performance. It depends also how you record it, just be confident and everything will goes well.
