Rediculous rockumentary on what could have been a fantastic review of the classic album. Although In Rock is certainly a milestone, this version is just a money jerker. Nothing new, even if you've never seen anything from Deep Purple so far, this is way from interesting.
Silly comments and wild guesses of "musicologists" of how this album presumably got together, back-up by a Blackmore interview from 1974 (that was his opinion than, now he would probably tell a whole different story).
The footages used here are shown in every dvd available (the granada tapes). Although the cover tells you that all tracks from In Rock are featured actualy only 2 songs/tracks get attention: Speed king and Child in Time, the rest is not highlited or mentioned at all.
So don't get fooled by the cover nor it's contents, this is an absolute NO HAVE in anybodies collection. Don't buy!!
Just to illustrate the sadness: The producers even used a photo of Glenn Hughes on the back (WTF)
