Northern Stage’s Jazz at the Junction series returns with another sizzling concert by Ray Vega’s Afro-Caribbean Jazz Ensemble at Byrne Theater in White River Junction, back by popular demand after a sold-out performance in January. The eagerly awaited encore — captained by the decorated trumpeter, University of Vermont lecturer and host of Vermont Public’s “Friday Night Jazz” — features everything from traditional jazz to the vibrant rhythms of Jamaica, Cuba and Puerto Rico. Expect innovative, contemporary takes on classics that’ll transport you to an island state of mind. ¡Fuegísimo!
