This chapter on Cuba’s avant-gardes of the 1920s and early 1930s focuses on writers associated with the Grupo Minorista and the Revista de Avance, examining their cultivation of porous intellectual communities and the attention they paid to everyday expressive forms in seeking to translate Cuban orality into writing. These writers, the chapter argues, sought new ways of characterizing Cuban experience and identity, engaging critically with their surroundings and positioning themselves as consequential cultural actors. The chapter portrays the Minoristas’ approach to the tertulia as an affective assemblage that thrives on difference and artful disagreement, welcomes international visitors, and, while being capacious enough to include women, clings to gender stereotypes. It also draws connections between the group’s tertulias and the international cosmopolitan interactions forged by the conversational qualities of the Revista de Avance, with a literary and linguistic “art of eavesdropping,” stylistic self-consciousness, interstitial participant-observer positions, and hierarchical views of culture projected by such Minorista writing as the crónicas and essays of Jorge Mañach.
