Prosthetic Records is pleased to issue legendary progressive metallers Watchtower's recent digital-only tracks on limited edition vinyl. The four tracks will be combined with one brand new song, creating the EP Concepts of Math: Book One. The release features 2010's digital single, "The Size of Matter," along with three additional tracks the band surprised fans by releasing across digital platforms late last year. An epic new track, "Mathematica Calculis" rounds out the EP.
"Before there was Dream Theater, there was Watchtower...In the 80's, Watchtower's "Energetic Disassembly" and "Control & Resistance" albums were hugely influential on me...I've been waiting almost 3 decades to see what they would follow these albums up with...and now the wait is finally over!" - Mike Portnoy
"The rocket scientists of progressive metal are back! Watchtower is one of very few that allow me to listen to music like when I was a kid - grinning ear to ear the whole time, wondering if I'll ever be that good when I grow up! Lose yourself in the music from the future, once again." Chris Adler, Lamb of God
