"Saying Pastorius is the greatest jazz-based bassist of all time would not be a stretch. Unfortunately, Pastorius' off-stage demons seemed to get in the way of sustaining that greatness. In addition to his drug addiction, Pastorius dealt with bipolar disorder and harbored a nasty temper. Pastorius, who collaborated with the likes of Joni Mitchell and Ian Hunter, died in 1987 at 35 due to injuries suffered in a bar fight, ending a celebrated musical career where his innovative funk harmonies on the electric bass are still an influence on bassists to this day."
