Hello

This is Nakajima from AZSTOKE Co., Ltd.

It is the purpose of this project.

For the sake of "destruction" that no one has ever recorded before!! A 3-ton mass of rock headed to SKYSQUARE

Our pursuit of "authentic sound" led us to overwhelming "mass."

In order to capture the earth-shattering sound of "destruction" that no one had ever recorded before, we decided to introduce new Foley equipment to SKYSQUARE.

What I found at a concrete specialty store in Nagano was a huge leftover concrete block, each weighing 600kg + 1200kg.

With a total weight of 3 tons, this "sound source" would normally be refused by a regular delivery service, but he used his own 3-ton dump truck to pick it up and unloaded it himself with a bulldozer.

We bring you a report on non-standard parts procurement that will redefine the conventional wisdom of audio production.

1. Check the texture and strength. Inspection at a concrete specialty store

In search of materials that would produce the ideal "destruction sound," we visited a concrete specialty store in Nagano Prefecture.

There, I saw the "remaining concrete blocks" I was looking for assembled into practical "retaining walls" and "fences."

The first thing that struck me was its overwhelming presence.

The neatly stacked blocks withstand the pressure of the earth and create a strong, sturdy wall that is unyielding. I learned that their original purpose was to support the ground and protect the boundary.

However, when viewed from Foley's perspective, it looks completely different.

"What kind of shock wave will be generated if these dense masses collide?"

"I wonder what kind of deep frictional sound will be produced when the rough surfaces rub against each other?"

By seeing actual construction examples, we were able to get a real feel for the potential of the blocks - in other words, how much mass energy they store.

2. 1.2 tons of "mass" loaded onto the truck bed. The tension of loading.

After the inspection, we load the selected blocks into the dump truck.

The main feature is a huge lump weighing 1.2 tons on its own.

It was lifted by a forklift and slowly carried onto the dump truck.

The moment the block was placed on the bed, there was a heavy thud and the dump truck's suspension suddenly sank.

Even though it's a 3-ton dump truck, there's still a unique sense of tension when a single point load of over 1 ton is applied.

The total weight of the blocks loaded this time was approximately 3 tons.

I checked the flex of the tires, felt the weight of the bike, and carefully made my way back to SKYSQUARE.

3. Take a break at the PA. Recheck the loading situation.

On the way back from Nagano, we stopped the car at a parking area along the way to take a break. When we got out and looked at the cargo area again, we were amazed at the amount of stuff we had loaded inside.

As it was carrying a total weight of 3 tons, the dump truck was lower than usual and looked solid and heavy.

It looks like an ordinary truck, but the bed is loaded with huge blocks of concrete.

These are the components that will be used to record sound.

Are there any abnormalities with the tires? Is there any risk of the cargo falling over?

I check all the way around and then get back on the wheel.

Maintaining this weight, we drive safely over the mountain pass to SKYSQUARE.

4. Place the "materials" on the ground. Prepare for unloading with a shovel.

After a long journey, we finally arrived at SKYSQUARE!

We immediately began unloading the huge concrete blocks that had been left piled up.

He placed his own excavator next to the dump truck.

Rather than trying to tackle 1.2 tonnes all at once, we will start with a 600kg block.

Even though it is only 600 kg, it is still a sufficient weight for a suspended load. We proceed while checking each and every movement.

Determine the center of gravity of the block and securely set the special tool.

In addition, a belt sling is used to connect it to the excavator arm, ensuring double and triple safety.

When working with such heavy loads, you can never be too prepared.

First, we carefully lowered this 600kg component onto the soil of SKYSQUARE.

5. Quietly lifting 600kg. Lifting with heavy machinery

Carefully operate the excavator's lever and slowly raise the arm.

The belt slings became so taut that they started to creak, and the next moment, the 600kg block that had been resting on the loading platform began to slowly rise up.

The block has left the dump truck bed and its full weight is now resting completely on the excavator's arm.

The sight of a 600kg mass in the air brings a unique sense of tension to the scene.

The aircraft is carefully rotated while minimizing shaking.

Slowly move towards the predetermined installation point.

First, I will focus on safely getting this 600kg down.

Once this is done, the next step will be components that weigh twice as much, 1.2 tons.

6. Taking on a 1.2 ton mass. Hardware and sling set

After successfully touching down the 600kg block, the truck next tackles the other remaining block in the loading compartment: a 1.2 tonne concrete block.

It was twice the weight of the block I had just lowered.

With such a large mass, even when setting up a single metal fitting, attention to its fit and stability becomes even more critical.

Specialized lifting hardware is carefully aligned and secured, and belt slings are used in addition to provide additional backup.

After checking the results, I returned to the excavator's cockpit. When this 1.2 ton component was placed on the ground at SKYSQUARE, it would add another new possibility for sound to our Foley field.

7. Six tons of "components" enshrined in SKYSQUARE

After two round trips to Nagano, all the components were finally assembled at SKYSQUARE.

Lined up on the ground were four 1.2 ton blocks and two 600 kg blocks.

A total of about 6 tons.

When you see the whole scene gathered in one place like this, you are once again amazed by its sheer mass.

These aren't just lumps of concrete. They're the foundation of the Foley that will support the sounds of destruction and impact that no one has ever recorded before.

What kind of life will these heavy components breathe into the field known as SKYSQUARE?

I'm looking forward to creating new sounds from now on.
