The latest on the investigation into the singer’s death, his estate and tributes:

11:12 a.m. ET: The Minneapolis Star Tribune reports that Warner Brothers has announced it will re-release nine of Prince’s biggest albums on vinyl, starting with 1985’s Around the World in a Day on June 21 with one or two albums a month to follow afterward. The project, started in conjunction with Record Store Day, was already in the works before he died.

The other albums scheduled for vinyl release include: 
Parade (1986), July 19
Sign O’ the Times (1987), Aug. 23
The Black Album (recorded in 1987, released in 1994), Sept. 20
Lovesexy (1988), Batman soundtrack (1989), Oct. 18
Graffiti Bridge soundtrack (1990), Diamonds and Pearls (1991), Nov. 22
The Love Symbol (1992), Dec. 13

10:14 a.m. ET: Footage of a  2014 Prince/Kendrick Lamar Paisley Park jam session turned up Monday on a Facebook page called the Prince Museum. The crowd at the private show was treated to a verse from Lamar before his host broke into What’s My Name from 1998’s Crystal Ball. (Prince reportedly intended that project to be part of a Sign O’ the Times triple album to be released in 1987 before Warner Brothers put the kibosh on that plan.)

8:23 a.m. ET:The Minneapolis Star Tribune reported Wednesday that Prince had been scheduled to meet with a California doctor in hopes of beating his alleged painkiller addiction. William Mauzy, a lawyer for opioid treatment expert Dr. Howard Kornfeld of the Mill Valley-based Recovery Without Walls, says the singer’s camp was in touch the night of April 20 seeking help for the singer’s “grave medical emergency.”

According to Mauzy, the California-based Kornfeld was unable to travel that day and so had dispatched his son and colleague Andrew to meet with Prince at Paisley Park to explain their plans for treating him confidentially. “The plan was to quickly evaluate his health and devise a treatment plan. The doctor was planning on a lifesaving mission.”

Andrew Kornfeld had taken a red-eye flight from San Francisco and arrived at Paisley Park at 9:30 a.m. CT on April 21.

The singer’s staff was unable to locate him for their appointment — though if his medical situation were truly that dire, it seems odd that they would have left him alone in the hours beforehand.

The Star Tribune‘s report says Kornfeld was one of three people present when his body was discovered that Thursday morning and that it was he who called 911 because everyone else was too distraught. This would explain the odd detail from the emergency transcript in which the caller was unable to provide the precise address of Paisley Park.

8:13 a.m. ET: Prince will be inducted into the Apollo Theater’s Walk of Fame during this year’s spring gala on June 13. The event, hosted by LL Cool J,will feature performances by the O’Jays, Leon Bridges and Andra Day.

Honorees, which have included Aretha Franklin and Michael Jackson, receive a plaque beneath the storied theater’s famous marquee.
