Kimberly Goss (born February 15, 1978) is an American singer and keyboardist, best known as frontwoman and co-founder of the Finnish metal band Sinergy.
Goss was born in Los Angeles to a Korean father and a German mother, who worked as a jazz singer. Shortly after, she went with her mother to live in Japan, before coming back to the United States and settling down in Chicago, where Goss was raised for most of her childhood.
Goss started her career in music early, debuting as a singer for the underground band Avernus at the age of fifteen. She went on to write and publish her own underground extreme metal fanzine at the age of sixteen, interviewing widely recognized bands such as Emperor, Darkthrone, Mayhem and Bathory, to name a few. At seventeen, she moved to Norway in order to pursue an offer she received to play keyboards for Norwegian black metal band Ancient. After recording one album with them, they went on tour with Dark Funeral and Bal-Sagoth. Two days after that tour ended, she was also invited to play keyboards and sing backing vocals on Therion's world tour in support of their Theli album. With Therion, she toured with bands like Amorphis, Sentenced and My Dying Bride as well as playing major European festivals like Dynamo Open Air.
