He's OK, but he isn't very good at lip sync, in my view.
No way that guitar's plugged in.
I think guitar cords and microphone cords have been gones from teh big leagues for many years.
I know that is Prince's symbol made into a guitar, but in silouette, it looks pretty phallic.
The only reason I thought the purple guitar solo was live is because it was out of tune - flat.
Though Prince's show was was good, I didn't appreciate the "Men In Tights" phallic silhouette.
Probably had a wireless pack on. It all looked and sounded live to me. Stadiums used to be very difficult to play live because of the *extremely* long reverb times, but with wireless in-ear monitors coming into widespread use, it's not such a big deal anymore.
