There are many ways to measure the greatness of a musician. You can talk dollars or awards or recordings or even high-profile gigs. But for the best of the best, put your money on the ones that other musicians talk about. Among Latin bass players, that's Ruben Rodriguez.
His first big gig was with Johnny Colon in 1979. Since then he's worked with Tito Rojas, Luis Ramirez, Ray de la Paz, Willie Colon, Dave Valentin, Charlie and Eddie Palmieri, Hilton Ruiz, Johnny Pacheco, Jose Fajardo, The Fania All Stars, and the late great Machito to name just a few. In the mainstream jazz field there's people like Grover Washington Jr. and Roberta Flack. And this is still a young man.
