I believe this record was one of the first successful attempts of melodic techno. (during the age of minimal)
Many are still desperately trying to recreate this sound.
I think the reason why this song is such a classic it’s due to the fact that it really captures what is techno.
You have the “main base” and yet you keep always hearing new “backgrounds sounds” that makes all even more appealing and embracing by the vibe and the rhythm
I honestly love techno and this classic gives me the possibility to enjoy it so much
