Sean Casavant, better known as Downlink, is an Electronic Music Producer and DJ from Kelowna. He has collaborated with Excision and Datsik. His most notable songs include "Ignition", "Existence VIP" and "Robo Kitty."

Downlink has been interested in music since an early age and started getting into Grunge when he was 8-years-old. Early in his teenage years, he began listening to nu-metal. In 2001, Downlink started producing and was mostly into making Drum and bass. Around 2006/2007 when Dubstep became popular in North America, Downlink started producing in that genre and began to collaborate with Excision and Datsik around that time.

In 2012 alongside Excision and Pendulum member KJ Sawka, they formed the dubstep supergroup Destroid.

Downlink has released music under labels such as Rottun, OWSLA and mau5trap.
