The legendarily free-spirited and charming William David Pearlman, better known as Poppa Neutrino, died Sunday. The documentary above, Random Lunacy, chronicles some of his adventures on land and sea, and many New Orleanians know him and his family band from playing on the streets of the French Quarter. Daughter Ingrid Lucia grew up at the front of the band. She posted an open letter about her father on Preservation Hall's blog. Information about the funeral is posted here.
