As many, i used to see MH as Purple's best ever, but time changed my mind. Though I continue believing that MH is one of the classic trilogy of the band (the other 2 are "In rock" and "Fireball", of course), I put it now on the 3rd. place. The earlier "In rock" is sharper and more interesting (sadly, the band does'nt do much of it in concerts, besides "Speed king" and "Child in time") and "Fireball" is a clever semi-progressive album, that sounds today almost fresh as it was in 1971. In its time, MH brought heavy metal to every home, like the Floyd's "Dark side of the moon", that introduced the world the progressive rock. Now we don't need it anymore. I'm not saying that the album is bad. It includes music that is made for live concerts more than a studio. "Highway star", "Lazy" and "Smoke on the water" sound much better in "Made in Japan". "Maybe I'm a leo" and "Pictures of home" are better in "Live in Olympia". So MH is an important album for the band, in historical point of view, but not that important to the 21st. centuey listener.
