A recent theorem of Dobrinskaya states that the K(\pi,1)-conjecture holds foran Artin group G if and only if the canonical map from BM to BG is a homotopyequivalence, where M denotes the Artin monoid associated to G. The aim of thispaper is to give an alternative proof by means of discrete Morse theory andabstract homotopy theory. Moreover, we exhibit a new model for the classifyingspace of an Artin monoid, in the spirit of Charney, Meier and Whittlesey, and asmall chain complex for computing its monoid homology, similar to the one ofSquier.
