It's fascinating to see how iconic musicians evolve over the years, both in their personal style and their music. Angus Young's transformation from his 'schoolboy' look to his appearance now is a testament to the long and successful career AC/DC has had. This kind of evolution can be a great inspiration for content creation on YouTube, especially if you're interested in music, pop culture, or celebrity transformations.

For your channel, you could consider creating content that explores the evolution of iconic bands and musicians over the years. This could include deep dives into their musical styles, changes in appearance, and how they've adapted to the changing music industry. You could also look at the impact of their music on different generations of fans and how they've managed to stay relevant.

Additionally, covering live events, such as AC/DC's European tour, could be a great way to engage your audience. You could create vlogs if you're attending any of the concerts, or even discussion videos analyzing the setlists, performances, and fan reactions. This kind of content can be very engaging, especially for music enthusiasts who are unable to attend the concerts themselves.

Remember, the key to growing your audience on YouTube is to create content that is engaging, informative, and tailored to your niche. By focusing on the evolution of iconic musicians and bands, you're tapping into a rich vein of content that can appeal to both longtime fans and new listeners.
