I don't know, the person managing Mad Cool's Instagram is replying to several comments from people asking for Linkin Park. If I had to guess, I'd say they'll be confirmed for both Mad Cool and Nos Alive.
IICON would be fine. It would be busy but not horrendous - IICON should be booking acts like them to help keep the rest of the SEC manageable
They could definitely sub park still tbh.
Theres no way they are headlining woodsies
