Tonight is the third and final night of Massive Attack at The Wiltern here in Los Angeles. Tickets are not sold out for tonight’s show as of now (10:18am), which means you have one more chance if you missed the first two sold-out shows.
If you miss them again, you can try your luck at the free outdoor mini-concert for the Jimmy Kimmel show tomorrow night. You can request free tickets online here. I don’t know how mini this mini concert is, but my sense is that you’d have a better chance at The Wiltern.
