Legendary 13th Floor Elevators' singer, solo artist and psych-rock originator Roky Erickson is tailor-made for documentary treatment. Making said film is a tough proposition, but You're Gonna Miss Me succeeds nicely. Owner of a potent wail and explosive songwriting, Erickson was equally owned by a litany of drug addictions and mental health problems (culminating in shock therapy and an unfortunate stint in a mental institution). Director Keven McAlester focuses not only on Erickson, but on the toll his life has taken on his family, who battle to enforce their own view on how to best save him.
