Strike Up the Band

 is a quest in the Fallout: New Vegas add-on Dead Money.

Overview
The objective of this quest is to get Dean to his position in Puesta del Sol where he will complete the circuit using his own body.

Quick walkthrough
You must escort Dean Domino to his assigned position to start the Gala event. When you get there, he refuses to stay unless you also activate two nearby security holograms for his protection. Alternatively, you can threaten to break his legs and leave him where he is, which works just as well. However, threatening or insulting Dean at any point in the game means you will have to kill him later in the Tampico theater inside Sierra Madre Casino.

Detailed walkthrough
If you opt to convince Dean to stay by making it safer for him, you will have to activate two holograms. The terminal to activate the first hologram can be found nearby, through the door opposite the one you just came out and down one level/floor. The second hologram is across from the first a little further away from Dean, on the second floor through a hole in the wall. Access to this terminal is through the Ruined Cafe which is further away (look for the door on your Pip-Boy map). Inside the Ruined Cafe, take the stairs up and go through the eastern door to Puesta del Sol South. From the balcony, walk across the rooftops to the hole in the wall where you will find the terminal to activate the second hologram.

The code for the auto. rifle upgr. internals can be found by the sparking cables where Dean is left.
