Public booking opens on-line today for this year's London Handel Festival, which runs from 11 March to 16 April 2013 with events mainly at St George's Hanover Square. Handel's penultimate opera Imeneo is staged at the Royal College of Music and there are also concert performances of operas by Telemann and Hasse, the annual Handel Singing Festival and a lunch time recital series. The festival closes with Handel's L'Allegro, il Penseroso ed ill Moderato with soprano Rosemary Joshua. See my preview of the festival. Booking details from the festival website.
