It's a wonderful day here in Sweden today! The sun is shining and spring is in the air, and when I say "spring" I mean pollen. Let's remedy that by 1) Staying indoors and 2) Introduce an all new biome with a grain of basalt, blackstone, and magma cubes! To spice it up, we also have some new fine tunes for you to listen to while traversing the Nether. Enjoy the snapshot!

Nether Music

We’re happy to announce that we’ve added three new tracks for the upcoming Nether Update, all composed by the very talented Lena Raine.

Rubedo will be played in the Nether Wastes

will be played in the Nether Wastes Chrysopoeia will be played in Crimson Forests



will be played in Crimson Forests So Below will be played in Soulsand Valleys and in Basalt Deltas

Two lines from Lena about the music. More to come in a separate blog post.

"One of the primary instruments in Minecraft is the piano, and so one of my challenges to myself was to see how far I could push the sound of the piano until it resembled other things entirely–again, that alchemical process."

"I wanted each piece to feel like a progression of emotions, or a journey from place to place within this other world. There's a degree of beauty to the Nether, but it is also terrifying in both its details and scale."

Take a portal to the Nether, and stay awhile and listen…
