Yep. Just some simple pure metal crunch.Grinder is such an underrated track.
Many have wondered why track 5 was not titled "Call For The Priest/Let Us Prey", as the opening line would suggest, but a 1978 bootleg of the Cambridge Corn Exchange reveals the band skipping the instrumental intro and only playing the second part, which Rob introduces as "Call For The Priest". "Let Us Prey" is an instrumental and the line, "Call for the priest, I'm dying..." is a lead-in to the second part of the song.
