I had never heard of Thank You Scientist before, but they were opening for one of the bands that I really like to go see live (Rivers of Nihil, seen them 5 times so far). HOLY SHIT they are so good. I have no idea how they ended up as the opener for that show, they're so different from the other bands on the setlist, but I am very glad I got to see them.
I saw Tesseract recently when I went to see Devin Townsend, that was an amazing show.
