With a bill featuring lots of acts that emphasize pop, blues, and Latin influences, a better name for the 19th annual Rosslyn Jazz Festival might be the “Jazzy” festival. But that’s no dis. Baltimore pianist Lafayette Gilchrist and his combo the New Volcanoes play an artsy blend of noisy bleats and unusual rhythms; the Spanish Harlem Orchestra layers big-band brass overtop clave percussion. Headliner Holly Cole is as likely to serenade with Brian Wilson, Joni Mitchell, or Tom Waits ballads as with those of Cole Porter, but the Canadian singer is no stranger to improvisation.
THE FESTIVAL STARTS 12:30 P.M. AT GATEWAY PARK, LEE HIGHWAY AND N. LYNN STREET, ARLINGTON. FREE. (703) 228-1850.
