do you mean their first single, or the first single with Karyu (which is I think Calvary) because he wasn't a part of their og line-up??? I find their entire first two albums basically unlistenable, and there's a lot of filler on every album of theirs
if you didn't like calvary and RIP/moment singles, there's really nothing for you there, they aren't an experimental band at all and recycle the same formula over and over.
I think they have one or two songs that have a distinct major despa feel, but I can't remember which ones they are exactly because kirito doesn't sound particularly well with this music direction and they aren't on par with karyu's past output.
