From the press release:

The Feldman Gallery will exhibit new work by Conrad Atkinson and Todd Siler in two separate installations. Both artists have been represented by the gallery for more than twenty years. Atkinson, an activist British artist who has influenced the direction of contemporary art, has engaged in controversial issues including industrial disease, Northern Ireland, and the proliferation of landmines. Siler, the first visual artist to receive a Ph.D. in Interdisciplinary Studies in Psychology and Art from M.I.T., provides an alternative vision of time, space, matter, and energy beyond the fourth dimension that takes into account the edgy, violent side of our creative nature.

There was a great show of Atkinson’s work at White Box in 2003.
