The term 'heavy metal' was still in its nascent stages, often used loosely and even derogatorily, to describe bands that pushed the boundaries of what was considered acceptable. Yet, these bands, through their innovative and intense sounds, were inadvertently laying the groundwork for a genre that would later define a generation of musicians and fans. This article delves into ten such albums, each a testament to the experimental spirit of the 70s, and explores how they, in retrospect, point towards the birth of heavy metal.

The Albums
- Black Sabbath - 'Paranoid' (1970)
What makes this album particularly fascinating is how it set the tone for the entire genre.

It's a classic that still resonates with fans today, and its influence on the development of heavy metal cannot be overstated.

This album is a prime example of how bands were experimenting with new sounds and pushing the boundaries of what was considered acceptable. It's a classic that still holds up today, and its influence on the development of hard rock and heavy metal is undeniable.

From my perspective, this album is a testament to the band's artistic evolution.
