We all know about fusion - the (sometime unholy) union of jazz and rock that tried to find a new audience for instrumentalists in the 1970s.  But there have always been, well, odder experiments with electricity in jazz, more like intrusions of the rock world than integrations, and we look at four rather varied examples in this here podcast.  Running the gamut from harmolodic blues-slinger to fusion axe-hero to . . . Herbie Mann? - these artists let the guitar off da hook and, possibly, into your hearts.  Herbie Mann - MEMPHIS UNDERGROUND ; James Blood Ulmer – BLACK ROCK;  Alan Holdsworth – NONE TOO SOON; Jay Hoggard - RIVERSIDE DANCE.
