Jackson died while under Murray's care five days later, in a bedroom just upstairs from the parlor where the meeting took place.
A much different Jackson appeared at the next scheduled rehearsal on June 23. "It was miraculous," Ortega testified.
"I was overjoyed at his energy, his state of mind, his enthusiasm," he said. "He had a metamorphosis. It was pretty extraordinary."
Murray told investigators he stopped using propofol to induce Jackson's sleep for the two previous nights -- after 60 nights of it. Jackson lawyers contend that is why Jackson was revitalized.
Ortega said Jackson appeared to have gotten "real sleep, organic sleep."
A sleep expert testified last month that someone can recover quickly from heavy use of propofol, which interrupts the normal sleep cycles. All of the symptoms that Ortega saw in Jackson on June 19 suggested Jackson had been deprived of real sleep for weeks, the expert said.
Jurors watched a video of "Earth Song," the final song Jackson performed at the June 24 rehearsal -- his last. "I love this piece," Ortega said as he watched.
"Our boy is gone"
Ortega was standing on the Staples Center stage in Los Angeles the next day when he got a call from AEG Live Co-CEO Paul Gongaware telling him Jackson was dead.
"Our boy is gone" Gongaware told him, he said.
"I think I was in shock," Ortega said. "I wanted to believe that it was some weirdo on the phone."
Ortega, who had worked with Jackson on other tours and projects, testified Tuesday that he would have been less likely to agree to direct This Is It if he had known what happened the day Jackson was to appear in London to announce the tour.
AEG Live CEO Randy Phillips testified last month that he "slapped" and "screamed" at Jackson because he was "nerve-racked" on that day, March 5, 2009. Phillips recounted that it was "a miracle" that a "drunk and despondent" Jackson finally appeared at the London event. AEG was hosting thousands of Jackson fans and hundreds of journalists for the anticipated announcement, which was to be seen live around the world.
"I screamed at him so loud the walls were shaking," Phillips wrote to AEG parent company CEO Tim Leiweke. "Tohme (Jackson's manager) and I have dressed him, and they are finishing his hair, and then we are rushing to the O2. This is the scariest thing I have ever seen. He's an emotionally paralyzed mess, filled with self-loathing and doubt now that it is show time. He is scared to death. Right now I just want to get through this press conference."
AEG Live executives did not tell Ortega about the incident when they approached him days later to direct the show, he said. He would have been "less likely" to accept the job had he known, because of his concern about how the preparation for the tour would affect Jackson emotionally and physically, he said.
Taj Jackson, Michael Jackson's oldest nephew, returns to the witness stand Thursday morning to continue his testimony begun last month.
The trial, which is in its 11th week, is expected to conclude sometime in August. The Jackson lawyers said they should call their last witness next week, which would be followed by AEG Live presenting its defense.
