Slipknot’s full performance from over the weekend at Knotfest was recorded and can be viewed above for those of us not fortunate enough to attend. Above is their set from the first night of the festival, below is night two. This gives us a glimpse into what we can expect from the Iowans on their upcoming tour in support of their latest offering .5: The Gray Chapter. The aforementioned record was released last week via Roadrunner.
