Hit the marker on the corner to begin.
Follow your objective to the dance party, then shoot out the speakers when prompted.
There are five speakers here, and five at the next location. They're all highlighted by target markers, and there's no LEGION resistance to your actions.
At the third party, you'll want to hack Aisha's tour bus.
As the hack progresses, you'll need to defend the bus from swarmtroopers and blitztroopers.
When the hack completes, so does the mission.
