Mosaic is an A Cappella group based in The University of Hong Kong (HKU), formed by students from different faculties and backgrounds. The name “Mosaic” resembles a picture made up of colored pieces of diversity; it was chosen to capture the very nature of the group – coming from different backgrounds, Mosaic-ers bring our individual uniqueness into harmonized pieces of alive and spirited music.
Established in July 2006, Mosaic is the first collegiate A Cappella group in HK to organise large-scale concerts and has been very active in the Hong Kong choral scene, staging numerous performances both on and off campus.
Mosaic held its first charity concert at HKU in December 2007. Since 2009, Mosaic has been holding full-house concerts every year for various charitable organisations: Crossroads, Samaritan’s Feet, Benji’s Centre, Project Little Dream, Soap Cycling and New Life Psychiatric Rehabilitation Association, receiving overwhelming appreciation and recognition. With nothing but their voices and passion, they realized and pursued their dreams through organizing their debut charity concert titled <<Tribute to the TV Box>>, which was unexpectedly well-received. Their second annual concert <<College 5.5>> vividly depicted their experience in the university. In 2011 concert <<Exclamation>> they shared their views towards life. In 2012, they did not talk about doomsday but they created <<iMosaic>> to share their experiences of using smart phones. In 2013, they shared views on dreams and hopes via music in their fifth concert, <<Flight Mosaic>>. In 2014, they shared the idea of “treasure every moment” with the audience in their concert, <<Fast Forward!>>
Outside Hong Kong, Mosaic made its debut international performance in the 2008 International Contemporary A Cappella Festival in Taipei, and was again invited to join the Festival in 2009. In March 2009, Mosaic was invited to perform in the Macau A Cappella Festival hosted by Macau University. In 2010, Mosaic was invited by Hong Kong Trade Development Council to perform in Shanghai, and in the same year, Mosaic participated in Singapore International A Cappella Championship and won the Silver Award. Mosaic also got first runner up in the same competition last summer. In addition, Mosaic won Championship at Asia A Cappella Festival Collegiate A Cappella Competition Champion for two consecutive years (2012 and 2013). These achievements have become a great form of encouragement to all members.
Mosaic is dedicated to promoting A Cappella music in Hong Kong, hence often appears on TV, radio, shopping malls and other major events.
