Shovel's Free Music Ripple Treasures - Featuring Engine, Kadavar, Wiht, and Kraken,

Engine
Quality sludge heftiness from Olympia WA. Stream the whole demo from their bandcamp page.

Kadavar
Retro styled fuzz fiends from Berlin, Germany. One to keep an eye on I feel....you heard it here first.

Wiht
Splendid epic UK heavy duty goodness with a hint of post whatever it is. Another up and coming band worth keeping tabs on.

Kraken
My demo of the moment. Full EP freely available via their soundcloud page, retro styled witchcraft-esque doom. Where they succeed is in the melody and execution. Don't miss out.

Doom on,
