Detailed walkthrough
When you get close to Trinity Tower (The tallest building in Boston), you will receive a distress call from Rex Goodman, who is trapped on the top of Trinity Tower. Once you listen to the broadcast, you will receive the quest Curtain Call.

Upon entering Trinity Tower, you will be attacked by Super Mutants and Mutant Hounds. Over the loudspeaker you will hear Fist (super mutant) taunt you. Continue up the stairs to the elevator and enter to go up the tower. Once you head up the elevator there will be more super mutants in the area as well as mutant hounds. Go up the stairs to be taunted by Fist (super mutant) again. Once you go up another level you will be confronted by more mutants. On that level is the next elevator up. (There is an elevator shaft that you can fall down that will bring you down four levels into a room that has a safe with an advance lock. This room can also be accessed by going down a level when you first exit the first elevator.)

Once you take the second elevator up you are almost at the top of the tower. Once again you will face more super mutants however there will be significantly more on the top so be prepared. Once you get to the top of the tower you will meet Fist (super mutant) who will carry a mini gun and can be a tough boss if your not prepared. In the cage at the top you will find Strong and Rex Goodman. They will be locked behind a master lock door however the key is in the Steamer trunk next to the weapons workbench.

Now that you have freed them go across the the construction elevator on the side of the building and press the button. From here the elevator will take you down a few levels but be careful because mutants will fire at you and the elevator will stop on purpose.

Once the elevator stops and opens the platform to exit fight your way down a level onto the next and final elevator.(Note that super mutants can throw grenades onto the elevator.) Once the elevator stops get off and work your way to the bottom of the tower the way you came in. Talk to Rex to finish the quest and potentially get strong as your new companion.

Notable Loot
After taking the first elevator into the tower there is a novice toolbox in the next to restrooms that you face strait ahead and to the right as well as a first aid box.

There is a locked novice locked toolbox in the room directly behind the elevator in the kitchen area. In the level below the elevator there is a door with an advanced lock pick, behind is a safe with an advanced lock and a terminal with a novice lock. Next to those are a caps stash and a med box. Once you go up the stairs from the first elevator to the room directly to your left will be a med box and two ammo crates. On the same level in a different room is a safe with an expert lock. Once you take the second elevator up, on the level you exit the elevator on will be a door(next to the on air sign) with an advanced lock, behind it will be a caps stash along with other scaled loot. On the level second to the top will be a radio room with a caps stash and med box.

On the top level the Melee Bobblehead is in the cage where Strong and Rex Goodman are held in.
