Now on cassette. "Minecraft" is the most popular and best-selling video game of all time. Created in 2009 by Swedish programmer Markus "Notch" Persson, this cultural phenomenon speaks volumes of our current zeitgeist's love for virtual spaces, but its unprecedented success couldn't be pinned on one factor alone. Countless layers of thoughtful artistry flow through its singular experience, not the least of which is its transportive soundtrack by C418, the project of German composer and musician Daniel Rosenfeld. Now both volumes - "Minecraft Volume Alpha" and "Minecraft Volume Beta" - have been packaged together in a double cassette edition.
