During today's dramatic opening statements, prosecutor David Walgren played a tape of Michael Jackson slurring his words while discussing upcoming concerts.

Walgren says Jackson was “highly under the influence of unknown agents” when Murray made the recording on his iPhone on May 10, 2009. Jackson can be heard saying in a low voice, “We have to be phenomenal. When people leave this show, when people leave my show, I want them to say, 'I’ve never seen anything like this in my life.'”

“View” co-host Sherri Shepherd tells HLN’s “Showbiz Tonight” she was shocked to hear Jackson's slurred words.

“That’s a side of Michael Jackson that we’ve never, ever been allowed to see, if that is Michael Jackson. It’s a little heartbreaking I think to hear something so private be so public.”

Walgren told the jury there is more to the recording played in court today. He promised the entire thing will be played later in the trial.
