Tommy Tallarico is releasing a two disc "Earthworm Jim anthology" covering the music from EWJ 1 and 2. It's, from my understanding, mostly or all going to be remixes by some people called OverClocked remix (I'd never heard of them until I found out about this, but I don't listen to game music hardly any at all). I think he said it should be out around some time next month. Of course, I can't wait
It was announced in a podcast that can be found here.
It's apparently their longest podcast ever from them (I wouldn't know, first one of theirs I've listened to..but I wouldn't doubt it. He announces it a little after 70 minutes in, I skipped the first 50 minutes to be honest..).
