This is a three-stage job, with Murray's part as the first one. Head over to the tavern and go inside the front door. Here, you'll need to disable the mixers by throwing the guards into them. There are two on the bottom floor and one on the second floor. Each of them will require two guards be thrown into them, so it might be easier to start with the second floor one. Just punch a guard once, stomp near his dazed body to pick him up, then toss him into the mixer.
Once all three mixers are disabled, you move onto Sly's portion of the job. Head to the shoemaker's place and go inside. Use the rope to get to the second level, where you'll need to use the Archer Costume to get to the middle of the room, then the other side. Note that you have to be careful of the rotating laser, as it can cut through your rope, so shoot the arrow when you know the laser is farthest away from it. Once you make it to the second platform, it's time for the Sixaxis control hacking mini-game. Make it to the end to shut down the machine.
The last portion of the job belongs to Galleth. Head over to the bakery and go inside. Knock down the door of either side of the furnace, then go to the back beam and use the hook there to launch yourself to the top of the bakery. You need to disable the three sub-generators, but once you do the first one, a 30 second timer will appear which will activate them all again. A defense system will also activate after each one, which include lasers and if you get hit by any, the system will reset.
To disable them, go to each sub-generator and use Galleth's Catapult technique to launch yourself up and knock the pipe out of the way. The first one will activate vertical lasers, which are easy enough to bypass. The second one will activate moving floor lasers, which are probably the hardest to get through. With the third one down, you will have to escape via the hole you used to get up here, and you'll need to avoid lasers that rotate around the room. Once you make it to the escape hole, the mission is complete.
