It is not accurate to say that black people stopped making rock music after the 60s. However, it is true that the number of black rock musicians decreased significantly in the following decades. This can be attributed to several factors.
One factor was the commercialization of rock music. As rock music became more mainstream, record labels and radio stations became more focused on promoting white artists. This made it harder for black rock musicians to gain visibility and recognition.
Another factor was the rise of other genres of music that were more closely associated with black culture, such as funk, soul, and hip-hop. These genres provided more opportunities for black musicians to express themselves and connect with their audiences.
Additionally, some black musicians may have felt that rock music no longer spoke to their experiences or cultural identity. Rock music originated as a genre created by and for white people, and it may have become less appealing to some black musicians as they sought to explore their own cultural roots.
However, there have been notable black rock musicians who have continued to create music in the genre since the 60s. For example, Prince, Jimi Hendrix, and Lenny Kravitz are all celebrated for their contributions to rock music. There are also newer black rock bands, such as Black Pumas and Algiers, who are gaining recognition in the genre.
In conclusion, while the number of black rock musicians may have decreased after the 60s, it is inaccurate to say that they stopped making rock music altogether. Factors such as commercialization, the rise of other genres, and changing cultural attitudes may have contributed to the decline, but there have always been and continue to be black musicians making important contributions to the genre.
