Hellthy: Indie Rock/Pop has become one of my favorite resources on the net to discover new music.
Just this last week they've posted the following selections:
The Clientele - An Hour Before The Light
Spoon - I Turn My Camera On
Neutral Milk Hotel - Holland 1945
Enon - Kanon
High On Fire - 10,000 Years
Timonium - Crushed Discs
Magnolia Electric Co. - The Dark Don't Hide It
They not only post the tracks, but also give links for each artist and their label.
And if you receive podcasts, they have one with all their downloads on it. You never miss a thing.
