A midnight movie cult classic. Watched this a hundred times in my teenage years. Notable (to me) for an alternate version of "Mob Rules" by Black Sabbath. I too have the double vinyl soundtrack album.
As for the audio, for what it is worth, here is the write-up at blu-ray.com - I don't know about you, but it makes we want to get this:
Sony touts the newly minted Dolby Atmos soundtrack as "a brand-new immersive experience utilizing enhanced sound effects and much more, supervised by producer Ivan Reitman." Purists may scoff, but they shouldn't. This is a wonderful listening experience. Bass is everywhere, offering extreme low-end engagement to a number of audio cues: the Loc-Nar rumbling about, heavy footfalls reverberating through the stage, the spherical alien spacecraft crashing and clanking upon impact, a volcanic eruption, and the B-52s lumbering through the skies are all amongst the low end highlights at work. The track offers full stage engagement, which includes a healthy supportive top end component. Discrete effects are not plentiful, but the sense of larger fill (along with the added surround-back channels) helps to deliver a spectacularly immersive experience that absolutely brings new life to this 40-year-old audio presentation. Music, from the eclectic assortment of top talent that contributed to the soundtrack, plays with exceptional clarity and effortless spacing. The front end dominates but the surrounds carry a healthy barrage of guitar riffs and other instrumentals. Lyrics tend to stay up front, but not exclusively to the center. The same goes for dialogue; it's largely presented from a natural front-center position but there are examples of both discrete placement and large-area reverberation. This is a first-rate soundtrack that is the perfect compliment to the visual experience.
