Through Hjort's connections and initiative, Disney artist Don Rosa used Gazette Bok for publishing his The Pertwillaby Papers and The Adventures of Captain Kentucky books.
In 2000, together with American Doug Hinman, he published Jeff's Book, an acclaimed annotated chronology of Jeff Beck's career, followed first in 2007 by Strange Brew: Eric Clapton and the British Blues Boom 1965–1970 and then by So You Want To Be A Rock'n Roll Star: The Byrds Day-by-Day 1965–1973.
[2] Classic Rock (magazine) felt So You Want To Be A Rock'n Roll Star was "convincing and exhaustive, it’s the ideal accompaniment for working through (or even starting) your Byrds collection",[3] while Record Collector wrote in its review that "this is an awe-inspiring work of scholarship".
[5] Hjort has also worked as a semi-professional guitarist, and toured and recorded two albums with Bygg Band, Norway's first cajun and zydeco group.
The band's second album was recorded in Crowley, Louisiana, in 1984, together with cajun and zydeco legends Link Davis Jr. (sax), Michael Doucet (fiddle), and Cleveland Chenier (rub board).
