Anna Homler (Los Angeles, 1948) is a vocalist, performance artist and composer, who takes bits and pieces of phonetic clusters from several different languages and combines them into a language that is all her own. She calls this technique "Linguistic Alchemy." She started out in 1980 with performance art, then around 1985 began to focus on the human voice. Anna travels the world with her music, singing with a wide array of different musical groups. She often combines these events with performance art and with found-object sculptures.
