Thanks to his sturdy bilingual flow, Miami rapper Pitbull has managed to build a career as a valuable utility man, adequately hopping from cameo to cameo on reggateon, dancehall, crunk, and R & B records. Unfortunately he tends to disappear on his own records, enlisting so many collaborators they tend to affect the quality of the music more than he does. On last year’s El Mariel (TVT)—a reference to the 1980 boatlift—the Cuban-American is joined by the Neptunes, Vybz Kartel, Fat Joe, Trick Daddy, and Bun B, among others. Stylistically all the bases are covered, and the subject matter ranges from anti-Castro rants to party jams to lothario boasts. But in the end it sounds more like a mixtape than the work of a single artist. Tomorrow night, May 26, Pitbull headlines a Latino-focused bill at the Aragon, a situation he should have no problem adapting to.
