When Brian Eno and David Byrne's My Life In The Bush Of Ghosts introduced a relatively broad audience to its sampling, electronic processes and haunted Middle East and African soundworld in 1981, Jon Hassell quietly seethed. Eno had sought the New York-based trumpeter out to make 1979's Fourth World, utilising his theories of a musical universe decoupled from Western hegemony, where Polynesian or Arabic tradition hitched a lift to the technological future. Hassell's second Fourth World album was therefore released later in 1981 with Eno's collaboration pointedly downplayed. This first ever UK reissue is diligently remastered, with the addition of Hassell's sleeve-notes and an extra track, ‘Ordinary Mind’, which is dominated by the ambient waves crashing on the shore. The album's innovation can't be heard wholly clear through the decades of world music and digital dominance which followed. Hassell's trumpet apprenticeship under Indian vocal maestro Pandit Pran Nath is, though, apparent in the instrument's breathy, denatured presence, sounding like banks of asthmatic Viking horns hovering over the tumbling polyrhythms of ‘Courage’, and the dub bass of ‘Dream Theory’. The Polynesian solo synth track ‘Datu Bintung At Jelong’ still isn't a mainstream proposition. While Eno took their gifts into the tents of Talking Heads and U2 (and was joined among rock royalty by this album's young engineer, Daniel Lanois), Hassell has stayed on the outside.
