Though it was dedicated to Blue Cheer, the album is arguably the most faithful tribute to the original spirit of Black Sabbath ever committed to tape. Vocalist Bobby Liebling always recalled Ozzy Osbourne with his uncultured, barely adequate vocal delivery. But on Day of Reckoning, it's guitarist Victor Griffin's ability to replicate Tony Iommi's guitar tone and playing style which is nothing short of amazing. The quartet is in top form, whether charging through the galloping title track, or taking their time on the wonderfully melancholy, drawn-out doom epic "Burning Saviour" -- very reminiscent of Swedish doomsters Candlemass. Day of Reckoning remains Pentagram's best all-around effort, and provides an ideal first glimpse at this very influential, but seriously overlooked group.
