To me, Deep Purple's finest studio and concert performances were achieved around the time "In Rock" and "Fireball" were recorded (1970-71). Indeed, it is my opinion that at that time the band played with a creativity and intensity unmatched by anything it produced before or since. That's why I was thrilled to discover this DVD, which represents some of the band's best live performances from that period. The collection includes performances in Granada (1970) and Denmark (1972). On the DVD, the Granada concert, which includes the songs "Speed King," "Mandrake Root," "Wring That Neck," and "Child In Time," is far superior to the Denmark concert. The picture and sound quality are top notch, and the performance is outstanding. I was particularly impressed by Ritchie's playing on Mandrake Root, which displays his wild, orgiastic virtuosity in all its glory. The Denmark concert includes the songs "Fireball," "Strange Kind Of Woman," "Highway Star," and "Lazy." On the DVD, this performance pales in comparison to the concert in Granada. The picture quality is poor (it looks more black and white than color), the sound is poorly mixed, and the performance doesn't match the intensity of the Granada concert. On the whole, however, I thoroughly enjoyed the DVD. It affords Purple fans with a glimpse of the band when it was at its best, and the commentary by various musicians and critics is a plus.
