Blackmore was at the top of his game. Lord and Paice were brilliant (as usual). The vocal tandem of Coverdale and Hughes was a defining moment in metal. And the songs were among the best in Purple’s sanctified canon. Glenn Hughes’ bass playing – as the title implies, was incendiary. The Voice of Rock's title track contrapuntal riffage: his soulful charisma which bolsters “Sail Away,” “Might Just Take Your Life;” his dense grooves on “Mistreated,” “What’s Goin’ On Here,” You Fool No One,” and the rumbling underpin of “A 200” – all set a benchmark.
