MJ Fanvention is going on at the Radisson Hotel and Star Plaza Theatre.
Memorabilia is on display, and Jackson's kindergarten teacher was meeting fans Friday.
She says it was clear he had talent even at the age of 6.
"He had perfect pitch, anything he sang was right on and his voice was particularly good, just light and pure his tone was good," said teacher Felicia Childress.
The Fanvention runs through Sunday.
