Aside from the enhanced visuals and audio track expected with the format, the Blu-ray edition of Jimi Hendrix Live at Woodstock features a wealth of bonus material, much of which is also included in the two-disc standard DVD release. The principal difference is that "A Second Look," a black & white version of the concert shot by an amateur, can now be viewed picture-in-picture along with the official version. The quality is imperfect, but it’s fascinating to see the show from a very different angle than those used by filmmaker Michael Wadleigh and his crew, who focused almost exclusively on Hendrix. Also worthy is "Recording Woodstock," with Hendrix engineer Eddie Kramer describing a process that was haphazard at best. --Sam Graham
