I said Sonder had to room to grow and damn was I right. Having it in my ears almost non-stop and listening to the 3D version in headphones, the CD version in my home system & car - I bump this album up to an 8.8/10. The sound just grows and grows on you and sucks you into another universe like Altered State* did. Buying the 2-CD set is just such a great value. I love that TesseracT are techy audiophiles like so many of us. Polaris, while I think was kind of a weak album, was still a great product as they gave you a DVD with the Hi-Res version of the album along with a regular CD. TesseracT and K-Scope Records are a phenomenal pair. While yes, it's 90% about the music the band produces, I think we need to start reviewing the product we receive from a band/label.
Aside from the product/production giving my rating a bump, the songs will also grow on you if you're unsure at first. Give the album a few listens in different environments and when you're in different moods - it's bound to be the perfect soundtrack in some part of your life if you're a fan of the Tesseract sound.
I was worried about the direction they were taking after Polaris. If Sonder is how their music is going to mature, we're going to have amazing albums from them for years to come.
*Altered State is a 9.5/10 for me
