JRock News gave a positive review and saying: "The Sign is a solid and loud metal album!

Crystal Lake was able to create something unique with a pleasant twist to their typical style, each song containing their own individual characteristics, ensuring an energetic and exciting listening experience throughout the entire album.

"[5] Alex Sievers from KillYourStereo gave the album 80 out of 100 and said: "Yes, one listen to Crystal Lake and it's clear that The Ghost Inside have been a very BIG influence on this band's sound, but they have just the right amount of added groove, heaviness and outside influences to differentiate themselves from The Ghost Inside/Hundredth sounding crowd.

Despite the odd misstep, The Sign is the first big chance that Crystal Lake have towards conquering the musical world beyond the shores of their home country.
