A little while back, Jimmy "Big Giant Circles" Hinsen released an album of music that he'd written for Mass Effect 2 but that didn't make the cut.
Now, he's put out a free remix album called Max Effect featuring music from Mass Effect 1, originally composed by Jack Wall, Sam Hulick, Richard Jacques and David Kates.
It is seriously good stuff. Here's the first track, called "ArmageddoN7."
(By the by, that is an excellently cheesy name for a Mass Effect remix tune.)
Love it. You can download the entire thing at Hinson's website.
