Sing into Christmas with Opera Siam published : 23 Dec 2020 at 04:00 The Calliope Chamber Choir. (Photo courtesy of Opera Siam) Opera Siam presents a traditional "Candlelight Carol Concert" on Christmas Eve tomorrow from 6pm to 7.30pm at the Banyan Tree Hotel's Ballroom, Sathon Road. This is a genuine, traditional European carol concert by Bangkok's multinational, multicultural Calliope Chamber Choir and Cherubim Children's Choir under the direction of maestro Somtow Sucharitkul. A staple of English choir culture, the format of Nine Lessons and Carols was solidified by the annual Christmas Eve event at King's College, Cambridge, which is broadcast by the BBC internationally every year. The Bangkok event is essentially the same formula, with carols from the 14th-century to the present sung by soloists and choristers of both choirs. The audience will be able to join in some of them too.
