I'm late, but I finally listened to the album, and... I'm really underwhelmed. I wasn't the biggest fan of Vector to begin with, but now Virus makes Vector sound like The Mountain in comparison
Obviously I've only listened to the album once, so it's not like I've spent a lot of time analyzing the songs, but after one listen I can say I found absolutely nothing memorable about it. My favorite song, melody-wise, might be Prosthetic, and that's saying a lot! Even Vector, with all the heavyness, managed to get good/memorable melodies and there's 4 songs that I really really like from it (the stretch from TGD to NBM). Here, I found it to be a really tiring experience, with a lot of samey-sounding songs, where I often felt like skipping them to see if there was anything interesting in the next one, but I tried not to.
As for the keyboards, I wonder where Diego was, because he's definitely not in the album
But, seriously, I think I heard the keys stand out like 4 or 5 times in an hour long album
Again, things could get better with more listens, but after going through the album from start to finish, I honestly have no desire to do it again. There's just so much great music out there that I enjoy a lot more, that I really don't want to invest more time in an album like this one
(not saying it's not good, it's just: 1. not really for me 2. not what I want when listening to Haken)
