Are We Soldiers was the last album that I really liked. Jonah Weingarten played keys and Brett was singing. The songs were great too.
Looking at Metal Archives, I can summarize each album:
I Wonder was next, and that was Dean singing for the first time. That's when I started to check out - it came out during the first year of the pandemic, and Dean kept posting about how prolific his songwriting was, and we were going to see releases come out frequently. I found it uninteresting.
Sorella Minore came out in 2021 and Nathan (Her Halo) sang on the first song, which was connected to Her Halo somehow. It was a 25 minute prog thing that I haven't listened to in ages. Dean sang the other 3 songs.
And the Beauty They Perceive was next, also in 2021. Also with Dean singing. That's the last album I listened to. It was just more of the same. Teramaze with Dean singing.
42 songs on major releases came out in just 3-4 years. To me, it seemed like quantity over quality, especially with Dean on vocals - just churn stuff out once or twice a year for the sake of it. There were even some singles and a live record too.
