Have been using this site for a while now, and discovered so-many excellent bands from it that I would never have discovered or herd before, all downloads are free and band-sanctioned, well worth checking out to discover new talent. Ps I am not a download freak and a I am strongly against illegal downloads (I own 1500 - 2000 original cd's), check it out and see what you's think.

That is an excellent site. I've been introduced to many awesome bands there as well.

Esoteric's albums are free downloads?

EDIT: ok, they just link to the streams on the official website.

If you right click the songs "save link as" and put .mp3 at the end it downloads the song.

Actually, on closer inspection... they're just free downloads, and in good quality. Those used to be low-quality streams (I think that's what Warlocks_amulet is talking about). Definitely get those if you don't have them, they are now officially the best free-download metal albums along with Demilich.

Only one song from the new one though (makes sense), although, weirdly, even the streams for the demo are gone. They used to have the whole demo up for download a long time ago. Maybe they're disowning it?
