Martí Sales debuted in 2005 with the book of poetry Huckleberry Finn (Moll, 2005), which won him the Premi Vila de Lloseta poetry award, and, since then, he has constructed an unclassifiable literary trajectory, transgressing the limits of each genre he has cultivated.

These include poetic prose (Dies feliços a la presó, Empúries, 2007), narrative (Principi d’incertesa, Males Herbes, 2015), the narrative poem La cremallera (Males Herbes, 2017) and even a dictionary, Aliment (Club Editor, 2021). He has also made a foray into essays with Ara és el moment (Amsterdam, 2016), a chronicle of the Catalan music scene, and is the regular translator into Catalan of authors such as Kurt Vonnegut, John Fante, Shirley Jackson, Vivian Gornick and Patti Smith.

In the field of music, he stands out for being singer and guitarist with the punk band Els Surfing Sirles. He has also contributed to cultural publications such as Time Out Barcelona and was co-director of the Barcelona International Poetry Festival (2010-2013) and Poesia i + at the Fundació Palau i Fabre. He is currently a member of the Barcelona Council of Culture.
