In the realm of classic rock, the 1970s were a time of experimentation and innovation, giving birth to a sound that would later become known as heavy metal. While the 1980s saw the rise of this genre, the roots of heavy metal can be traced back to the 70s, where a few key albums laid the foundation for the hard-hitting, high-octane music that would define the decade. Personally, I think that the 70s were a golden age for rock music, and these albums are a testament to the creativity and talent of the artists of that era. What makes this particularly fascinating is that these albums, while not necessarily considered groundbreaking at the time, have since become revered as pivotal moments in the evolution of heavy metal. In my opinion, the 70s were a time when rock music was at its most diverse and innovative, and these albums are a perfect example of that. From the epic, classically-inspired sound of Led Zeppelin's 'Presence' to the proto-speed metal of Budgie's 'Never Turn Your Back On A Friend', these albums showcase the range and depth of the decade's musical offerings. One thing that immediately stands out is the influence these albums had on the development of heavy metal. Bands like Judas Priest and Iron Maiden were inspired by the ambitious and epic sound of Led Zeppelin's 'Presence', while the speed metal of Budgie's 'Never Turn Your Back On A Friend' would go on to influence Metallica's early work. What many people don't realize is that the 70s were a time when rock music was at its most experimental, and these albums are a perfect example of that. The decade saw the rise of glam rock, prog rock, and proto-metal, all of which would go on to shape the sound of heavy metal in the 80s. If you take a step back and think about it, it's clear that the 70s were a time when rock music was at its most diverse and innovative, and these albums are a testament to that. The sound of these albums is a blend of different genres, from the hard rock of Starz to the glam rock of Kiss, and it's this diversity that makes them so fascinating. This raises a deeper question: what would the 80s have been like without the influence of these 70s albums? A detail that I find especially interesting is the fact that many of these albums were initially panned by critics, but have since become revered as classics. This suggests that the music industry can be fickle, and that what is considered groundbreaking at one time may not be seen as such in another. What this really suggests is that the evolution of music is a complex and ever-changing process, and that the influence of these albums on heavy metal cannot be overstated. In conclusion, the 70s were a time of great musical innovation, and these 10 classic rock albums are a perfect example of that. From the epic sound of Led Zeppelin's 'Presence' to the proto-speed metal of Budgie's 'Never Turn Your Back On A Friend', these albums showcase the range and depth of the decade's musical offerings. They laid the foundation for the heavy metal of the 80s, and their influence can still be heard today. So, if you're a fan of heavy metal, I encourage you to explore these albums and discover the roots of your favorite genre.
