Really liked the reaction. Like someone said, yes there probably was a backing track which they sing over. Sometimes they do that, sometimes they have live bands or even a full orchestra. You mentioned the voice effect and I've noticed they do a great job occasionally adding subtle effects to enhance a certain sound they want to achieve. It's just another talent they have and since they write and produce mostly everything it's pretty impressive. And I agree Felix does wear accessories and styles very well and that includes changing up his hair color. He tends to be blonde a lot but he's had most every color lol. I think his natural color is more of a brown/black.They tend to change up their looks and styles to fit an mv or a comeback just as you mentioned with the color contacts Changbin wore at the beginning of the mv. Sorry you'll miss Lolla in Chicago! Maybe they'll come back around on the upcoming tour...

yeah, most idols tend to use a backing track, especially when they are performing in a stadium or a music show type situation. SKZ sings live as much as possible, but sometimes you need the backing track in case there are audio issues, or if say someone is sick. Bang Chan, the leader, did a really good breakdown of live singing vs backtrack vs lipsync a couple of years ago. I hope you are ready for the new album on July 19th! I can't wait.
