Let There Be Rock, the purest manifesto of AC/DC's hard rock

"Let There Be Rock" is an AC/DC song released in 1977, included as the title track of the album of the same name. It's a direct statement of what the band understood by hard rock. The song is built around a very simple yet extremely effective, repetitive, and energetic riff, which serves as the foundation for one of Angus Young's longest and most intense solos, considered by many to be one of the best of his career.

The lyrics present the birth of rock as if it were a biblical event, using religious references to describe how rock arrived in the world as an inevitable, powerful, and almost sacred force. This approach reinforces the idea of ​​rock as something destined to exist, not as a passing fad. Musically, the track is fast, loud, and unadorned, with a raw production that reflects AC/DC's intention to sound direct and aggressive, distancing themselves from any commercial softness.

This song marked a key point in the group's identity, consolidating the classic AC/DC sound based on simple riffs, constant rhythm and defiant attitude, and became a fundamental part of their concerts because it summarizes their philosophy: to play hard rock, without compromise, and to push the energy to the limit.
