via vgermuse: "photo from the NY Times of Marshall Allen, 85, at the Abrons Arts Center in NYC playing an early version of the Steiner EVI (all analog). The reviewer writes, "He also coaxed loopy frequencies from an electronic valve instrument, making use of a pitch-modulator knob; its timbre suggested a steelier, less vocal-sounding theremin." He is the focus of the Vision Festival happening this weekend in NYC."
Update:
here's a link to the article in the NY Times.
Note Marshall Allen played with Sun Ra in the Sun Ra Arkestra.
"Mr. Allen, who turned 85 last month, has been a member of the Arkestra for more than 50 years: he joined the ensemble almost at its origins, spearheading its reed section and faithfully minding the various edicts of its namesake leader. When he took the helm himself in the mid-1990s, after the deaths of Sun Ra and the tenor saxophonist John Gilmore, Mr. Allen set his sights on continuity. He has kept the band together and working, with one eye trained on the legacy of an expressly future-oriented music."
