A hard rock band with an average age in their 70s is still going on world tours at that age?

Nostalgia concerts? No. This is a real world tour. The name is AC/DC.

Formed 53 years ago in 1973, there's hardly anyone who doesn't know this band, and their continued presence is legendary enough to be noted in history.

Looking at the members' ages, Angus Young, born in 1955, is the youngest at 71, while Brian Johnson, born in 1947, is nearly 80.

If you list the entire lineup, they could just be residents of a retirement community.

In a normal world, at this age, they should be going on hospital tours, not concert tours.

But the reality is they fill stadiums with tens of thousands of fans, shredding guitars and getting the audience to jump.

AC/DC started in Australia in 1973. They have been pushing the blues-based rock and roll, often referred to as 8-bit rock and roll, for over 50 years.

These days, bands start exploring genres after two albums, change their image after three, and by four albums, fans are reminiscing about the good old days.

But AC/DC has just stayed the same from the beginning to now. It seems they haven't found a reason to change.

In a way, it's stubbornness, and in another way, it's brilliant branding.

And then there's Angus Young. This guy is still running around the stage in a school uniform. He's 71 years old.

At an age where knee problems are a concern, he's running around stadium stages. This isn't just about stamina; it's like he's from another species.

Like Mrs. Lee Gil-yeo from Korea, there must be something hidden behind his superhuman youth, but no one has figured it out yet.

AC/DC's official album sales exceed 200 million. They rank in the top five for sales in rock band history.

Considering they are from Australia, it's honestly an unbelievable number. A band from a country with a population of 20 million has circled the globe twice.

Back in Black is not just a classic album. To explain the history of hard rock, you have to start with this album.

But the truly strange thing about this band is that they haven't stopped since that legendary album.

Usually, after releasing a classic album, it's time to take a break, but this team just keeps going.

The fan base should age along with the 70s bands, but when you go to their concerts, you see 20- and 30-somethings jumping along.

It's a scene where both the father's generation and the children's generation are jumping together.

This isn't just generational empathy; it's proof that the music has simply devoured time.

Most bands are said to last a long time if they make it to 10 years. If they last 20 years, they're considered legends.

This team has surpassed 50 years and is still going strong.

These days, music rises quickly and fades just as fast. This team started slowly and is still not gone.

From the perspective of aging... honestly, it's a bit annoying.
