Since the early 1990's, Ischar's work has focused on the potentials of video and sound in ever more distilled manifestations. Following large multimedia installations such as Orderly (1994) and Wake (1996), Ischar turned to more minimal forms. His 1997 work for InSite (San Diego/Tijuana) used a high school basketball court as locale for a multimedia meditation on adolescent homosexual desire.
His 2001 work, ground, uses twenty-four channels of audio to replicate the sound of a gallery floor being swept. His 2005 public installation, Water Music, explores the relationship between personal and artistic histories of the Pacific rim cultures in which Ischar lived as a child.
Since 2006, he has been producing single-channel videos around issues of cross-generational male intimacy and psychological/social loss. These Include Back the Way He Came (2006), Bask (2007), brb (2007), and Forget Him (2009).
