Butchering the Star Spangled Banner.....
......has become a bit of a contest of late. It's one thing to get creative with it (e.g. the Jimi Hendrix version). It's another thing entirely to try to jazz it up with repeated melisma substituting for real singing.
Lip syncing has also become quite the thing. Yo-Yo-Ma also had a backing track at the previous inauguration.
I'd be pretty angry if I had paid money to see someone in concert and found out they were just miming to a pre-recorded vocal track.
