In recent years, rendition has become as popular as performance in the sense of providing musical, dramatic, or other forms of entertainment. Both words mean "the accomplishment or execution of acts, feats, or ceremonies": "The tenor's rendition (or performance) of classical songs was well received." Rendition is now something of a "vogue" word, perhaps because it stresses the unusual or distinctive qualities of a performance or interpretation given by leading popular singers and public entertainers. Recommendation: use performance unless some spectacular or unique quality should be noted and stressed.
