Prince. The Purple One previously played successful residencies in the New York area in December and January to tremendous acclaim. Now he’s brought it to Southern California. The Forum, 3900 W. Manchester Blvd., Inglewood. Saturday and various dates. $25-$205. https://www.ticketmaster.com.

Lil Wayne He may not be the first rapper to boast of wanting to literally eat his rivals, but in 2008 he was the top chef in rap’s kitchen. “Tha Carter III” was practically the only good news from the business of selling CDs that year. Now after a stint in prison and a venture into rap-rock with “Rebirth,” Wayne is back with a tour humbly dubbed “I’m Still Music.” Honda Center, 2695 E. Katella Ave., Anaheim. 7 p.m. $73.10-$193.70. wwwticketmaster.com.

The Big 4 Festival Hot on the heels of Coachella, metal music’s biggest names — Metallica, Slayer, Megadeth and Anthrax — are set to invade the Empire Polo Club for more than seven hours of head-banging mayhem. A sighting of all four acts in the same set is as rare as a snowball’s chance in — well, you know where. Empire Polo Club. Avenue 51, Indio. 2 p.m. $99. thebig4festival.com.

Grilled Cheese Invitational Need another reason to hit this up? Evan George and Alex Brown, the indie-rock food writers behind the blog Hot Knives, are hosting a chef stage.
