Medicine played in Memphis right before I got home from college one summer, but my brother Josh and our friend Andy saw them and even visited with them at the Admiral Benbow Inn (just recently demolished). They learned that Medicine’s wicked guitar feedback was achieved by running Brad Laner’s guitar through a four track and turning all the knobs up. We spent that whole summer trying to get a four track to mimic a distortion pedal with no success. Brad Laner, we determined, was a genius. Which is probably why I recently Tivo-ed the movie “The Crow,” just so I could see that scene of Medicine playing “Time Baby,” trying to get a glimpse of his guitar setup. Now Laner and fellow guitarist Christopher Willits, as North Valley Subconscious Orchestra, are releasing another feast of guitars on Ghostly’s digital download-only album The Right Kind of Nothing. More melodic feedback, anyone?
