The party had a political education system for its militants and sympathizers and a bookshop, and promoted popular local papers and newsletters. It managed to record and launch protest and patriotic singers and musicians, some of which later have gained wider audiences and become a part of the Latin American Nueva Trova musical trend, such as Roy Brown, Noel Hernandez, Antonio Caban-Vale "El topo", Pepe y Flora, Andres Jimenez "El jibaro", and the Frank Ferrer band. The PSP also had links with theatre groups, like Anamu.
