Underworld have revealed a previously unheard track titled ‘Birdstar’ – and it’s a belter.

The track is a demo from the  ‘Dubnobasswithmyheadman’ period and will form part of the remastered re-release of the album to celebrate it’s 20th anniversary. Many of the track’s elements were subsequently used in other songs, right up until ‘Second Toughest In The Infants’, and also utilised in a number of classic Underworld remixes, including Bjork’s ‘Human Behaviour’ and ‘Black Sky’ by Shakespears Sister.
