The song is very good, catchy and with different and interesting parts. The production is like for Firepower, only the intro has a different vibe.
I really like the main riff of the song, the melodic verses (like for Traitors Gate from the previous album), the bridge with the double drumming and Rob's screamy vocals before the solos (the Maiden-esque melody before them too; that's the intro melody but a bit different), the solos are strong (alternating between melodic and wild ones is always good; they remind me a bit of some old ones, the harmony too), the double harmony is just perfect after them and Richie's outro solo and Rob's scream are great to end the song. The intro strangely fits the song. As a single, it's one of their strongest.
I expected the chorus to be simple and I'm not a fan of it, but I guess it needed to be urgent. The second repeat of the chorus in the outro is with more lyrics and is better. The drumming is also different. I don't like the theme of the song and expected something with a darker sound, which I'm glad it's not with tbh.
Overall, it sounds like classic Priest (indeed Firepower/Painkiller vibe). Rob sounds great. Richie brings that melodic vibe with his riffs, solos (4 solos - 2/3 from him, 1 from Glenn and maybe 1 from Andy?) and the two different harmonies. The melodies (guitar and vocal) are everything for the song. I'm really happy that the song has so many different parts.
-> It seems to be the album opener.
