You should get THE BLUE ALBUM from 2004 – it’s their best work, I think, taking both studio albums and scores into consideration. And with both Sparks and Lisa Gerrard adding their contributions!
I finished my walkthrough of the other albums again, up to 2023’s OPTICAL DELUSION, and I still can’t connect with any of them like I can the four mentioned. But they have potential, and I’ll no doubt continue to give them chances.
