In the early '70s, Japanese musicians and critics were seriously engaged in what is now humorously referred to as the ‘Great Japanese rock controversy’. Simply put, this was a debate on whether lyrics in Japanese were acceptable at all, with many arguing that English was the one and only rock lingo. Now, when a new generation of artists raised in the age of the internet is emerging, the English-Japanese controversy feels less relevant than ever. Today’s up-and-comers care little about some imagined ‘authenticity’, as they all speak the same language – the language of tunes.
