Pedrito Martinez is such a heavy guy that Wynton, Waters, and Winwood as well as Springsteen, Sting, and Simon have either dropped in on him or invited him on stage or to a session…and those are just the names that grouped well by letter. The Cuban percussionist, singer, bandleader and Santeria practitioner now has a steady gig at a hip new Manhattan joint Subrosa where I spoke with him and captured some performance.
