Heavy Metal Parking Lot, a mid-'80s film documenting lifeforms that once orbited around Judas Priest concerts, has been circulating on shitty-quality VHS bootlegs for years. I just watched it for the first time last night -- and it blowed mah mahnd. BB friends Coop + Ruth turned us on to it, and the film recently became available on DVD (along with Neil Diamond Parking Lot, and lots of other good stuff). Zebraman FTW!
Amazon Link for DVD purchase.
Update: Oh dear god there are ringtones.
