I was there yesterday in front, been aware autotune could come any second, but nothing happened. At least I did not hear it, nor my wife which was watching the show from balcony.
Yes his voice was much stronger in 2009, what makes you say that it wasn't a great year for him vocally then?
since 2008 his voice is getting weaker, i've seen a lot of people say that 2009 wasnt a good year for chester overall. but this concert is one of the best LP concerts i've seen, and his performances with DBS are also great.
It's definitely a shame that auto tune is highly evident from this performance. Can hear it all over GATS. Other than that they still killed it!
