The distinguished Cuban-American playwright Eduardo Machado has created a touchstone piece by taking a one-act play with music, written in 1982, and turning it into a full-length, two-act musical. His Rosario and the Gypsies, with songs by composer Rick Vartorella and lyrics by Mr. Machado and Mr. Vartorella, was a short, wild rock 'n roll play with music about the backstage romances and melodramas of a hippie performance troupe in southern California who were devoted to the art of change. Its songs were a combination of street pop and 60's-70's rock. It was produced in NYC by Ensemble Studio Theater in 1982 and it got Machado recognized as a writer to be reckoned with. Machado and Vartorella have now revised the piece and completed its story, adding a second act, in which we learn the future for its characters.
