I found a torrent for Into the Unknown and am listening to it right now. Pretty fuckin bad, but very interesting. It's from 1983 and I guess they broke up after it for a couple of years and then got back together and eventually did Suffer. You can totally hear with the vocals that they were headed into the classic sound they created from Suffer on. But the music (and tons of cheesy keyboards) are really bad - BUT it's still totally Greg's sweet voice and harmonies - some if it almost sounds like their more recent stuff (minus the keyboards of course.) Interesting.
Oh, also check out this BR video I'd never seen: Dream of Unity - was from a euro live album they did that had a couple of new songs. Not the best BR song but nice video!
