Yesterday I bought the special edition of Classic Rock with a tribute to Deep Purple´s Machine Head.
I think that all artists involved are great, especially with Black Label Society "Pictures of home" because I do not like at all this band. Also I've loved Kings of Chaos (Elliot, Steve Stevens, Duff McKagan and M Sorum) playing "Never before" and Metallica have surprised me in "When a blind man cries".
The only negative point I put on The Flaming Lips with a grotesque version of "Smoke on the water". I assume they wanted to do something original and different ... but is that the version is unhealthy and disastrous.
