IDLES brought out slowthai during their Kendal Calling set at the weekend.
The two acts are developing a close relationship - both were nominated for the Hyundai Mercury Prize, and clowned around for cameras afterwards.
In a manner of speaking, they're actually competitors, with the winner set to be announced at a London ceremony on September 16th.
You'd never think so with this camaraderie, however: IDLES invited slowthai onstage at the climax of their Kendal Calling set.
Charging into 'Television', frontman Joe Talbot told the crowd: “Always be yourself, unless you can be Slowthai… then always be Slowthai.”
