It's the autotuned/pitch-corrected microphone she uses for all her performances these days lol. You can tell in the difference between her & Lizzo's mic. It may sound 'good' for newer fans, but I miss her raw & grundgy vocals versus this unnatural overly processed sound.
Yeah - she spent that time away after the critics killed her CTRL live performances and the voice is voicing! I love that she did the work and it’s paying off!
too bad sza didn't come to the special tour in austin!!! like five days before i saw her live at ACL fest and was wearing the ctrl shirt i got to see lizzo.
