In December, the organizers behind the Rock And Roll Hall Of Fame announced its latest round of inductees. As usual, it was a pretty tepid class — Steve Miller, Chicago, Cheap Trick, Deep Purple, and N.W.A., who probably only got in this time around because of the blockbuster biopic that was made about them. Now, the institution has announced a few of the special guests who will be doing the actual inducting: Kendrick Lamar, Metallica’s Lars Ulrich, the Black Keys, and Matchbox Twenty’s Rob Thomas. It seems pretty obvious that Lamar will be ushering in N.W.A., but what about the rest?

The Rock And Roll Hall Of Fame ceremony will take place on 4/8 at Barclays Center — tickets are available here.
