According to Burning Ambulance (Phil Freeman is a trusted source), reedman Arthur Doyle has passed away.
A favorite of mine indeed - worked with Noah Howard and Bill Dixon as well as his own groups in the '70s, guitarist Rudolph Grey in the '80s, and recently as a leader in some admittedly quite strange settings with his own childlike vocal tunes blended with free improvisation. He was falsely imprisoned in France for a stretch in the '80s (IIRC) and seemed to have some personal struggles, but he was and is a true American original well worth celebrating.
