In the 1960s he had a weekly music column and wrote jazz reviews and roving reports on assorted cultural themes (with illustrator Klaus Albrectsen) for the Danish daily newspaper BT.

Two books of his thin columns of poetry-like texts (in English) were published by Forlaget Bebop: Terninger, Tonefald: 12 Lines, 36 Off-Lines (2005) and Stilhedens Cymbaler (2007).

In the 2000s, he was invited to use his voice and texts with the Copenhagen free-jazz trio Clinch (Claus Bøje on drums, Peter Friis Nielsen on bass guitar, Christer Irgens-Møller/keyboards); they released the 2006 album "Dice, Done" (also with Lotte Anker (saxophone) and Steffen Poulsen (electronica)).

In 2005 he founded the collaborative improvised music group "Instead Of", composed of Lori Goldston, cello; Angelina Baldoz, trumpet and flutes; Jaison Scott, drums; and Ulrich on voice/texts and "bag of tricks", releasing in 2007 the album "Live on Sonarchy".

[7] In 2021, at the age of 92, Ulrich released the jazz record, "Oakland moments: cello, voice, reuniting (rejoicing)", which featured him playing alongside cellist Lori Goldston.

[8] Ulrich began painting in 1971 when the Lions Club of Copenhagen asked a variety of politicians, actors, writers and others to make "a blue elephant" for a charity exhibit to benefit a senior center in Denmark.

[11] In 2011, Ulrich began development with choreographer-dancer Beth Graczyk and composer-musician Angelina Baldoz on the dance project "Cacophony for 8 Players",[12] which premiered in 2014 in Seattle.
