What I noticed that BigHit does with a lot of their reposted concert content is that they tend to go back to tune the vocals or fix things up from the original performance.
Like I distinctly remember Jimin missing a line in Fly To My Room (which hey, it happens!) and Taehyung’s mic quality being completely fucked— but in the new bangbangcon version of Sowoozoo, everything is nice and clean and polished.
I compared the two performances to see if anything had changed, and sure enough it had. I was sort of grateful because my biggest complaint about Sowoozoo was the mic quality, the audio overall of that concert was not great; quiet mics, spotty sounds, and a jarring volume imbalance between the members really distracted me at that time.
But yes, I just found it a little interesting! It’s just something I’ve noticed on bangtan concert content for the past couple of years!
