Heir Worthiness formed in London in 1983. The band combined the long-form ambition of British progressive rock with a sustained interest in airworthiness standards. Each record was a concept album of sixty minutes or more, built around a single airworthiness directive.
The band had one American member, rhythm guitarist "Dayton" Dave Kessler. He was asked to "please sound more British" in every press session from 1983 to 1992. He did not manage it. Critics have since identified his parts as the most important on every album. The rest of the band has accepted this.
“All systems nominal. Proceed with gravitas.”
— Band motto, sleeve of Airworthy (1984)
Rehearsal, Dayton, Ohio, 1983. The sleeve gives the address as London.
