Every once in a while, there's a band that gets everything right: the right sound, the right look, and, more important, the right vibe. The genre-defying Kayakman fits perfectly with our city's eclectic ambiance. The group's Latin American musicians love mixing things up, fusing sultry tango with Caribbean rhythms over a solid punk-rock beat. A main reason for the foursome's tight clatter is singer/guitarist's Leonardo Vega's past gig as an axe man for Manu Chao, the international gypsy superstar. In the past couple of months, the band has scored a weekly show at Churchill's on Tuesdays that has been attracting hundreds of new fans to the group's biweekly shows on Española Way in Miami Beach. With a new album — the excellent Let's Go Fellas — Kayakman seems poised to be one of the most popular bands in the city.
