American rock was, and still is to some extent, a closed shop. REO Speedwagon, Toto, Boston, Foreigner all those bands, and I wouldn't be able to tell which from which.
This quote highlights the limited diversity and a sense of sameness within American rock bands, especially during a certain era. It suggests that many bands sound alike, possibly due to restrictive industry practices or similar musical influences. Such homogenization can make it challenging for listeners to distinguish one band from another. It also hints at the exclusivity within the industry, where emerging artists might struggle to break through or innovate amidst established patterns. The statement encourages us to consider the dynamics of musical innovation and the importance of originality within a genre that is often perceived as vibrant and authentic.
