No identity crisis here: just a slice of mutated UKG from a pair of dance music’s favorite collaborators.

As he promised on Twitter, Kieran Hebden kicked off the last hour of his marathon eight-hour Rinse FM set with a previously unreleased collaboration with Burial. The pair have teamed up several times since 2009, releasing ‘Nova’ last March; this new-to-us track follows their MO to a tee.

The Rinse FM session follows an eight-hour marathon at London club Fabric, and also featured appearances from Caribou, Anthony Naples and Floating Points.

Listen below to the untitled track. For more Four Tet, check out our review of his brand new Beautiful Rewind and explore his ten finest deep cuts.
