‘Tis the season for loads of unreleased and rare music courtesy of the fine people over at Youtube.

Following yesterday’s find of a veritable pantheon of live stream rips from Deadmau5’s live streams, one of our readers alerted us to an entirely new playlist of gold. This time it’s Pendulum.

Known on Youtube as Hjalte RMC, he’s been curating a diverse collection of unknown tracks and remixes since 2011. Scouring the likes of Reddit, Youtube, and other fan-generated music forums, he’s successfully created the largest store of unheard Pendulum bliss that we’ve ever seen.

Over 40 unique videos show the behind-the-scenes timeline of Pendulum’s work, some stretching all the way back to the early 2000’s.

Take a look at a new chapter in the history of modern electronic music, and let us know your favorites!
