Very professionally produced karaoke (except a couple artists who actually played instruments). Lots of leds and lasers. One song per artist, with a varied mix of styles. Awkward drivers introduction at the end.
All in all, not bad, if those kind of shows are your thing. Not as cringy as Miami.
I think practically all of them (if not all) sang live. That's why I jokingly said it was a karaoke. (No disrespect intended). I truly prefer live voice over a backing track than straight playback with people mimicking the performance.
