Jaco Pastorius. Pastorius was 35 years young when he passed away in 1987.
Geddy has cited Pastorius as one of his influences over the years, and used a fretless Fender Jaco Pastorius tribute bass to record "Malignant Narcissism" on Snakes & Arrows.
Tentatively titled "Jaco", the film is being financed by Metallica's Robert Trujillo. For more info visit USAtoday, or visit the film's Facebook page. - Thanks to RushFanForever for the headsup!
