A lost album from David Bowie might seem like the holy grail of pop music yet the peculiarly named The Gouster, raised from the archives, is right here as the centrepiece of a handsome new 12-CD box set, Who Can I Be Now? (1974-76). The 27-year-old Bowie stares from the sleeve, draped in a newspaper and the American flag, looking unusually anxious, as if wondering what posterity might make of a collection of recordings he, himself, deemed unfit for release. He needn't have worried. The Gouster turns out to be a minor joy from a major artist, a soulful stepping stone on the way to inventing a whole new genre of music.Between 1969 and 1980, Bowie released 13 astonishing albums. In the two-year, 1974-76, period alone he put out three albums: Diamond Dogs, Young Americans and Station to Station - all included in the new box set in various mixes. And now, it turns out there's more.Well, sort of. Recorded in that same "American" period, during a break from touring over two incredibly productive weeks in Sigma Sound Studios, Philadelphia, The Gouster has been restored from original mixes by producer Tony Visconti.It was Bowie's first stab at meshing his grandstanding melodies and arty hauteur with funk and soul, and includes versions of four songs that would make their way on to Young Americans.Gouster is slang for a black American streetwise, jive-talking, sharp-dressing dude.The album displays a raw, live quality with several tracks extending into long jams.Finally given its moment in the light, The Gouster is unlikely to become a belated part of the canon, but it is nevertheless a welcome testament to the real heart beating at the centre of Bowie's pop genius...
