UPDATE: It will be Prince at his most intimate – just his voice, a piano and a microphone in concert at Paisley Park in Chanhassen.

He'll do two performances – 8 and 11 p.m. – on Thursday. Tickets are sold out.

This is the format of a tour he planned to take to Europe last fall before the terrorist attack in Paris derailed Prince's plans.

In a press release, the Minnesota music icon explained his motivation for this solo foray: "For several reasons. For starters it is a challenge. You have to try new things. With the piano it is more naked, more pure. You can see exactly what you get."

On social media, Prince has been touting this "Gala Event" for a few weeks without releasing details other than it would take place on Jan. 21. He did post photos showing a remodeling of the concert space to include carpeting and comfy chairs.

Tickets went on sale Saturday at www.paisleyparkafterdark.com. Since tickets sold out quickly, the site has been taken down.
