Murray's 2007 book, The Rush to Here, a sequence of 57 sonnets, reworks a number of traditional forms (Petrarchan, Spenserian, Shakesperean sonnets) into a new rhyme scheme that employs what the poet refers to as "thought-rhyme", conceptual and semantic pairings that work on the level of synonym, antonym and homonym to create intertextual meaning, as opposed to the sound bonding of traditional aural rhyme.
Murray's 2010 book of aphorisms, Glimpse, was a Canadian bestseller.
His 2012 book, Whiteout, contained a poem titled Song For Memory, first published in The New Welsh Review, that was adapted by the band The Once for their 2011 album Row Upon Row of the People They Know (a phrase taken from the poem).
In 2014, Murray founded the online poetry journal NewPoetry, a site that ran until 2018.
In 2020, Murray founded Walk the Line and Front of the Line, an online poetry school and community dedicated to teaching poetry as a learnable skill rather than as an academic pursuit.
