Chevalier Theatre welcomes the El Gran Combo, one of Puerto Rico’s greatest dance bands, for a stop on their 60th Anniversary World Tour. Led by pianist and musical director Rafael Ithier,  the 13-piece salsa group inspires dancers with its horn-punctuated Latin rhythms and lush vocal harmonies.  Officially named “Ambassadors of Our Music” by the Puerto Rican Senate, El Gran Combo’s many hits include such classics as “El Menu” and “Timablero.” Tickets are $45 to $100 through the Chevalier Theatre website/Ticketmaster. Tickets also may be purchased, free of online ordering fees, at the Chevalier Theatre Box Office, which is open on Fridays and Saturdays from noon to 6 p.m., as well as two hours before every Chevalier Theatre show.
