Adam Crane, director of public relations for the Los Angeles Philharmonic, wrote in an email to The Los Angeles Times that she "felt dizzy and had spotty vision when she realized that she could not continue." Grimaud had wanted to resume the concert but was too weak, and was treated by an onsite medical technician.

She told Crane the incident was connected to a heart arrhythmia for which she had seen a physician earlier that day; she added that she intended on seeking the advice of her doctors in Europe.

The June 17 recital was a rescheduled engagement; she had cancelled her January 10 date because of back problems.

Born in Aix-en-Provence, France, the 37-year-old Grimaud is known for her commanding interpretations of German Romantic repertoire and her captivating physical beauty. She has studied with Jacques Rouvier at the Paris Conservatoire, Leon Fleischer and Gy‹rgy Sšndor. Her debut recording, made at age 15, of Rachmaninoff's Second Sonata and Etudes-tableaux Op. 33 catapulted her career into the big leagues.

Grimaud is also widely known for her extra-musical interests and accomplishments: she has authored two books and co-founded the Wolf Conservation Center in South Salem, New York. She will release this year a CD of works by Bach.
