This CD captures Lux Interior playing dj one night (July 1984) at a Hollywood radio station in the guise of "The Purple Knif" (a nod to 60s radio legend Ghoulardi).
If you're familiar with the Born Bad series, you know exactly what to expect...& if that's your kinda thing, then--in the words of the old Cramps chestnut--"You got good taste!"
Unfortunately, this CD is a French issue, so I couldn't tell you how to get one (I found mine in a pawn shop).
Update 28nov1998: Apparently this CD is available through CD Now. Bad news: it's US$28.
