Pure

A lot of luck is required for this.

Best track is the Phu Temples which can be found on the main menu under Single Event.

Fill your bar as quickly as possible and perform high scoring tricks in quick succession. This actually only took me 10 minutes and a few restarts.

You can see on the video that I got super lucky with this and hit the rock which easily could of broken my combo if I landed it by crashing.

Best of luck!
