Amphilium - 404 - Not Found (Enigma Revisited)

The Company You Keep - Amphilium

The scorpion of love strikes again, more venomous, more potent than ever. End Of Time may sound like the apocalypse, but it’s actually the birth of something new: a euphoric world of slow trance visions.

The track has already stirred up a storm at events across Mexico. Santiago’s music moves people - he showed us that years ago at the Amselcom Showcase in Mexico City, where an atmosphere of pure ecstasy swept over the crowd. That night left a mark on us, and from that moment, we knew we wanted to release something with him.

Now, years later, the moment has come. We’re proud to present his debut single with us: End Of Time. It’s the closing of one chapter, and the beginning of another. And we couldn’t be more excited.

By @alacrandelamor from Mexico City.
