Thought I’d post up this rather fine collection of tunes that is available for free download courtesy of Ghostly International . The album is called “Ghostly Swim” and is available for download here as the full album or choose individual tracks. Some great tracks on there, definately worth a download.
A few sample tracks:

Michna~Triple Chrome Dipped

Another free sampler album is available from K7 records. Available to donwload from here, the only payment required is an email address. Again a good variety of stuff to check out:

Milosh~Awful Game

Herbalizer~You’re Not All That
