Argentine rocker Gustavo Cerati remains hospitalized after suffering from cerebral ischemia following a concert in Caracas, Venezuela.

The 50-year-old singer, who was long the frontman of Soda Stereo (with whom he reunited to tour in 2007), had performed a show on May 15 as part of his "Fuerza Natural" tour, named for the album released last year.

A statement in the artist's Web site said he had suffered cerebral ischemia "as a result of a rise in his blood pressure," and he remained hospitalized in stable condition. The statement said he will remain under observation and undergoing exams for several days.

Executives from Cerati's label, Sony Music, were not available for comment.

As a member of Soda Stereo, Cerati fronted one of the most successful rock groups in Latin America before launching a successful solo career in 1999. Cerati's "Fuerza Natural" tour had already taken him to eight countries, including the United States and Mexico, prior to his Venezuela stop.

Last December, Sony tested its Music Ticket + program with a Dec. 19 Cerati show in Buenos Aires, where fans who bought tickets received a card with a special code that enabled them to download the album for free. According to a Billboard report, of the approximately 15,000 fans who attended the show, 47% of them downloaded the album, underscoring the loyalty of Cerati's fanbase.
