[Machine Translation] The concept of "pop" is similar to Andy Warhol's pop art concept of mass production and consumption, while incorporating the idioms of non-human, near-future, factory-made, etc. that the techno-pop of the 70's aimed for. The concept of Sister is to move towards "pop" while incorporating idioms such as inhuman, near-future, and factory-made, which were aimed at by techno-pop in the 70s. Their sound is experimental, but still catchy and full of British taste, with a touch of pop and Beatles' DNA! Their future is very promising.
