i mean that's just it, there are some prog metal bands with vocalists who have power behind their voices - LaBrie used to be one, for example, and Haken, Caligula's Horse, and Leprous are all bands that are as vocally driven as they are instrumentally driven. It also helps that they each have their own styles and sounds, which I didn't really get the impression that Odd Logic do from what I heard. They're instrumentally talented enough, there was the occasional instrumental moment that caught my ear first listen for sure, but the songwriting seemed kind of all over the place & especially that 23-minute "epic" just felt like a long string of disconnected ideas.
Considering a lot of what I've been listening to lately is post-hardcore, which is also very vocally-driven, weak vocals are just a flat turn-off for me nowadays, I suppose
But being instrumentally technically impressive by itself isn't enough for me either, there just wasn't a ton that hooked me in. It doesn't seem particularly worse or better than the average prog metal these days though. I prefer this over the djenty djent no-melody all-rhythm trends or the textureless melancholy of TesseracT ripoffs though, for what it's worth.
