1967/ 1976
Interesting compilation based on Gull Records albums (Rocka Rolla and Sad Wings Of Destiny).
We begin the analysis by the songs of Rocka Rolla. I do not dare to consider Rocka Rolla a Metal Album. Rather, I consider Rocka Rolla as one of the 10 Prog Rock albums of all time. Except for the song "Caviar and Meths" Rocka Rolla is all in this compilation. Sounds strange listening to these songs. Because many songs have aged badly. Yet they have a huge fascination. The sound is dated, the production is painful.
Sad Wings Of Destiny is full present. The sound is aged good but the production is... Better that the production of Rocka Rolla... But... Remain a great painful production. In this case the music is Heavy Metal. Great Music... Victim Of Changes and Tyrant are great evergreen of Rock, not only Heavy Metal evergreens.
So... The Collection is Rocka Rolla + Sad Wings Of Destiny in one album. And, for sure, commercial compilation.
