In 1975, Dalglish finished a video art project that consisted entirely of interviews with fifteen of his artist friends talking with Byrne — with Byrne offscreen the entire time doing most of the talking. The point of the video wasn't what Byrne said, but the body language of the listeners. The name of the seven-and-a-half-hour video was "Talking Heads, a 7.5 hr Conversation Installation." Participants in the video included Talking Heads drummer Chris Frantz, and artists Jeff Koons, Jeff Turtletaub, and Vito Acconci.[6][7][8] The video was exhibited in 1979 at The Kitchen in New York.[4] The full video appears to be lost, with only a few short excerpts having survived.[6]
In collaboration with guitarist and songwriter George Elliott, Dalglish created the short-lived rock performance group CONTAINER in 1979. The group consisted of a five-person band, with Dalglish as vocalist and lyricist, plus a 10-year-old female singer, dancers, and a film and video crew. A recording of their music has since been released on a CD. One of their songs, "Three Wishes", was recorded by Klaus Nomi on his 1982 album Simple Man.[9]
Dalglish began painting in the 1970s[10] and had his first art exhibition in 1979 in New York City.[4]
In the early 1990s, Dalglish originated the word "morphoglyph" to define his painting. He has explained that it "combines the word "morph", growing or changing forms (from Morpheus, the son of the god of sleep, the form of dreams) with the word "glyph", an incision or cryptograph – secret writing, the language of the soul. I think morphoglyphs provide abstract painting with a surface that seems to say, "art is the art of becoming art."[11][12]
Dalglish received a 2006–2007 Pollock-Krasner Foundation grant.[13] He has exhibited in galleries including OK Harris, Match artspace,[14] Barbara Braathen, and Florence Lynch. Dalglish's morphoglyphs have been cited by art writer Lee Klein, among the works of Jackson Pollock and David Reed, as part of the trans-filmic lead into the art of Hyper-texture.[15] He was included in the exhibition "I colori del rock," which ran in 2009, from January 29 through March 3, at Pavesi Fine Arts in Milan, Italy.[16]
