spent writing and recording a new album and playing live rarely. 2000s The early part of 2000 was spent touring with Soulfly which culminated in Chris being asked to perform the song "Bleed" with Soulfly at the Sydney Big Day Out. The Smile album surfaced in early 2000 during a national tour with Slipknot. The album was released to critical acclaim on Roadrunner Records' Australian development label Dark Carnival.
