I believe that GleenO is talking about doing a bunch of takes and then comp for a perfect take. To me it’s less time consuming and if you now how to do your edits properly you cannot hear it’s a combined take. Also keep in mind that today it’s pretty normal to record stuff riff by riff and not the whole song in one take. Then if you for example combining takes for the perfect chorus of a song, it’s just a matter of copy/paste for the next chorus.
