PINK FLOYD LETS EVERYBODY WRITE! Bass-centric tribute artist Rick Thompson grooves with us in a cave while we discuss this transitional album. How do you pronounce “Ummagumma”? Which member of Pink Floyd looks like a horse? Is the Grand Vizier a Pict? How did Nick Mason sneak his flautist wife in on what was supposed to be a totally solo outing? Which comes first, meat or pudding? Would this work better as a soundtrack? Who owns “The Madcap Laughs” but not “Dark Side Of The Moon”? How many copies of this album were sold that only had the second disc played once or twice? Set the controls to the heart of the sun this week on Detours and Outliers.
