The question of when "rock music died" is subjective and difficult to answer definitively. Rock music has undergone numerous transformations and evolutions since its inception in the 1950s and 1960s, and it continues to be a popular and influential genre to this day. Therefore, it can be argued that rock music has not "died," but has instead undergone changes and adapted to different cultural and technological developments over time.
That being said, some experts in the music industry point to the 1990s as a significant turning point for rock music. During this decade, alternative rock, grunge, and punk rock were popular, and many classic rock bands from the 1960s and 1970s saw a resurgence in popularity. However, by the end of the decade, pop and hip hop music had begun to dominate the charts, and rock music was increasingly seen as a niche genre.
The 2000s saw a continuation of this trend, with pop and hip hop remaining the dominant musical styles in popular culture. Additionally, the rise of digital music and the internet changed the way that music was distributed and consumed, and many traditional rock fans felt that the genre was being left behind.
Despite these challenges, rock music has continued to evolve and influence other genres. For example, the 2000s saw the rise of emo and post-grunge, which blended elements of alternative rock with pop punk and emo. Additionally, some classic rock bands from the 1960s and 1970s continue to tour and release new music, and many younger musicians continue to be influenced by these iconic artists.
In conclusion, it is difficult to say exactly when rock music "died," as the genre has undergone numerous transformations and evolutions over time. Some experts point to the 1990s as a turning point for rock music, but the genre has continued to evolve and influence other genres in the decades since. While it may not be as dominant in popular culture as it once was, rock music continues to have a dedicated fanbase and continues to be an important and influential genre in the music industry.
