Machine Head have created a monster! I was so disgusted with "Supercharger" that I thought they could never recover. However, for many bands I believe this to be the age of re-emergence, and Machine Head have re-emerged in a big way."Through the Ashes of Empires" is brilliant. It's heavy, overwhelmingly catchy, extremely aggressive, very well structured, and excellently titled."Imperium" will hopefully remind people just how catchy Machine Head can be, and realise just how the band was at the front of the metal scene back in '94. "Elegy" is probably my favourite song on this album. It's deep, well vocalled approach is something new and refreshing.There isn't a bad song on here, and Phil Demmel is an excellent replacement because Luster was about the worst guitarist I've ever heard. "Descend the shades of night" leaves the album on an amazing high, or low, depending on your outlook.Machine Head returns, I'm very thankful. What a band.
