Yes, That Man is Playing an Amplified Jug
My enthusiasm for Complete has resulted in getting a couple of their songs stuck in my head -- an experience that, like the dental work of Curtis, their singer, is not at all pretty.
Fortunately I've discovered a well-done reworking of some rare video footage of the 13th Floor Elevators, with the original recording (to which they are lip-syncing) dubbed in to replace the tinnier soundtrack heard elsewhere:
The drummer for the band I was in Austin also played with Roky for a while in the mid-1980s. A live recording of the Elevators from 1966 that he gave me a few years ago will be blasting while I do chores today. The amplified jug is a bit more prominent than what you usually hear from the studio session. It really adds something special to "Roll Over Beethoven."
UPDATE: Jerome Weeks alerts me to a forthcoming book about the Elevators.
POSTSCRIPT: Is it just me, or does Roky look like the young Dean Stockwell in this video? Roky himself was about 18 when it was filmed.
