This is probably going to be a controversial post. Let me first say that Lost In A Lost World is a great song that took a couple listens to click, but after it did... wow. I love Bruce’s vocal flourish during the verses. That said, the rest of Steve’s songs are a big swing and miss for me. Hell On Earth is decent, but I don’t find many redeeming qualities to either DOTC or The Parchment. They just plod along pointlessly. They’re just there.
There are three vastly superior songwriters in the band right now: Bruce, Adrian, and Janick. Jan is a tough call cause his songs are usually (always?) co-written, but they’re better and more to-the-point than Steve’s solo writes, so I’d say the core songs are by Jan.
For me, this album is spectacular up until DOTC hits. I find myself bored for the last thirty odd minutes of music. But then Hell On Earth has the best Maiden moment since perhaps the 80s when Bruce sings “Love in anger, life in danger”. Incredible. Perfect. Genius. So Steve is capable of greatness, he’s just a lot like another Steve. Stephen King suffers from pointless verbosity that a good editor would correct. Steve Harris suffers from the same problem. Nobody can or will tell him no, or worse, they have but he refuses to listen.
