Per the previews from the listening sessions, the second track and single
Cusp of Eternity was said to be the most straightforward or "simplistic" rock song on the album. I must say it doesn't sound all that simple. I mean, sure, the guitar riffing in the main verses is pretty basic, but the change up towards the end and that beastly guitar solo is great. Also, holy hell can you hear the Ritchie Blackmore/Rainbow influence. The biggest suck here is the damnable two month wait for the rest of the album to drop.
