The guys from Tek Syndicate[1] seem to be ok with piracy of their albums however they do ask you to buy it if you think it's good and worth the money.

I think that approach is the best one to have. Pirate it try it out if you really love it please buy it.

You can find it here[2] i know it's a pain to find a link to the album on the main site I need to send them a message about it.
