when will i dont wanna hear it mission start

The mission I Don’t Wanna Hear It starts after you complete “Rebel! Rebel!” and wait for Kerry to call you. A walkthrough source says you’ll then meet Kerry at the Riot area, with the rendezvous objective appearing around 7 PM in-game once the call triggers.

What to do

• Finish Rebel! Rebel! first.

• Wait for Kerry’s call after that, which may take about 24 in-game hours or a bit longer depending on your save timing.

• Go to the marked meetup near Riot and wait until 7 PM if needed.

If it is not starting

• Some players report that simply waiting 24 hours outside Kerry’s place or reloading an earlier save after Rebel! Rebel! helps the call trigger.

• The quest can also depend on completing the prior message/call chain from Kerry, so a delayed start is usually timing-related rather than broken.

TL;DR: It starts after “Rebel! Rebel!” once Kerry calls you; expect roughly 24 in-game hours, then meet him near Riot at 7 PM.
