Winning the praise of his fellow young authors Stephan Roll and Ilarie Voronca, he was criticized by prominent literary figure George Călinescu, who accused him of "priapism", based on Bogza's irreverent tone and erotic imagery. It was also during the late 1920s that Bogza began touring the Prahova Valley, becoming a close observer of local life in the shadow of the oil industry. He had a conflict with Tudor-Miu in August 1928, after the latter modified a poem Bogza sent to be published in "Câmpina"—the two reconciled later in the year, and later wrote a special poem for its one-year anniversary. His collaboration with Pană, Roll, Ion Vinea, Simion Stolnicu and others led to the ad hoc establishment of a literary group, which was defined by writer and critic Camil Petrescu as "the revolutionaries from Câmpina" (after the town where Bogza spend much of his time). Among other writers who joined Bogza in publishing the five issues of "Urmuz" were Voronca and the Dadaist Tristan Tzara.
