Organizers of Festival Imperial confirmed the last four bands, including the likes of Seal and Café Tacuba, that complete the line-up of 10 artists to appear at this year's event.

Argentine rockers Babasónicos and Mexican alternative group Café Tacuba will feature on the first day of the festival. They will share the stage with previously announced acts including Tico band Le*Pop and internationally acclaimed U.S. groups Incubus and Smashing Pumpkins.

The second day will see British-born singer-songwriter Seal and Mexican group Zoé play along with Costa Rica's Porpartes, Spanish-American pop star Enrique Iglesias and British 1980s icons Duran Duran.

Tickets are now on sale for the event, to be held at La Guácima de Alajuela on April 19 and 20.

“We have brought together really top-drawer artists who will give us performances that would be worthy of an international festival in the developed world,” said Carlos Cañas, Brand Manager of Imperial.

“At Cervecería Costa Rica we are very pleased once again to offer Costa Ricans and those from neighboring countries the possibility of enjoying two days of concerts with some of the all-time greats of music,” he said.

Meanwhile, “La Ruta Festival Imperial,” which promoters describe as “a way to bring music and the public closer together and to build up the atmosphere ahead of the main event,” is continuing. The coming week will see events held at Jazz Café in San Pedro tonight, La Birrería in Heredia on Thursday and the Mundoloco festival in Sabanilla, East of San José, on Saturday.
