★★★ DVD: THE MAN FROM MO'WAX London's 90s kingpin of underground instrumental hip hop
 
      
      Sometimes absorbing, sometimes morose documentary on London's 1990s kingpin of underground instrumental hip hop beats 
  
            Recent years have seen a boom in music documentaries. They are, after all, relatively cheap to make and have a readymade audience. Their narratives are usually similar, and so it is with The Man From Mo’Wax: fame and glory, followed by a fall from grace, followed by self-reflection, absolution and a glimmer of fresh success. What many of them also offer is a sense of wild passion, of the raw, unfettered power of music. This film has little of that.
