Celtic art is associated with the peoples known as Celts; those who spoke the Celtic languages in Europe from pre-history through to the modern period, as well as the art of ancient peoples whose language is uncertain, but have cultural and stylistic similarities with speakers of Celtic languages. Celtic art is a difficult term to define, covering a huge expanse of time, geography and cultures. A case has been made for artistic continuity in Europe from the Bronze Age, and indeed the preceding Neolithic age; however archaeologists generally use "Celtic" to refer to the culture of the European Iron Age from around 1000 BC onwards, until the conquest by the Roman Empire of most of the territory concerned, and art historians typically begin to talk about "Celtic art" only from the La Tene period (broadly 5th to 1st centuries BC) onwards. Early Celtic art is another term used for this period, stretching in Britain to about 150 AD.
The ancient peoples now called "Celts" spoke a group of languages that had a common origin in the Indo-European language known as Common Celtic or Proto-Celtic. This shared linguistic origin was once widely accepted by scholars to indicate peoples with a common genetic origin in southwest Europe, who had spread their culture by emigration and invasion. Archaeologists identified various cultural traits of these peoples, including styles of art, and traced the culture to the earlier Hallstatt culture and La Tene culture. More recent genetic studies have indicated that various Celtic groups do not all have shared ancestry, and have suggested a diffusion and spread of the culture without necessarily involving significant movement of peoples. The extent to which "Celtic" language, culture and genetics coincided and interacted during prehistoric periods remains very uncertain and controversial.  Celtic art is associated with the peoples known as Celts; those who spoke the Celtic languages in Europe from pre-history through to the modern period, as well as the art of ancient peoples whose language is uncertain, but have cultural and stylistic similarities with speakers of Celtic languages.  The term "Celt" was used in classical times as a synonym for the Gauls (Keltoi, Celtae). Its English form is modern, attested from 1607. In the late 17th century the work of scholars such as Edward Lhuyd brought academic attention to the historic links between Gaulish and the Brythonic--and Goidelic--speaking peoples, from which point the term was applied not just to continental Celts but those in Britain and Ireland. Then in the 18th century the interest in "primitivism", which led to the idea of the "noble savage", brought a wave of enthusiasm for all things Celtic and Druidic. The "Irish revival" came after the Catholic Emancipation Act of 1829 as a conscious attempt to demonstrate an Irish national identity, and with its counterpart in other countries subsequently became the "Celtic Revival".

IN: Ai Carina Uemura (Zhi Cun  Ai  karina, Uemura Ai Karina, born November 2, 1981), known mononymously as Ai (Japanese pronunciation: [ai], stylized as AI or A.I. ) is a Japanese-American singer and songwriter who was born in Los Angeles. Ai spent her childhood in both Kagoshima, Japan and Los Angeles. She debuted as a singer in 2000, later moving to Def Jam Japan and rising to fame with her album 2004 Ai.

Ai was born in Los Angeles in 1981. Her father was Japanese and her mother was half Italian-American and half Japanese. She moved to Kagoshima in Japan when she was 4, and went to elementary school and junior high school in Japan.  Ai was motivated to become a singer in her early teens, after singing at a cousin's wedding, having many people ask her if she wanted to be a professional singer, and hearing a gospel performance at the First African Methodist Episcopal Church of Los Angeles in 1993. After graduating from junior high school in Japan, Ai returned to Los Angeles for high school, enrolling at Glendale High School, however found high school difficult due to never formally studying English. After making it through the audition process, she switched to the Los Angeles County High School for the Arts, majoring in ballet. She became a member of the school's gospel choir. In 1998, she performed in a gospel choir at a Mary J. Blige concert at the Universal Amphitheatre, performing of "A Dream." In the same year, she appeared as a dancer in the music video for Janet Jackson's song "Go Deep."  In 1999, she joined an Asian girl group called SX4, who were produced by George Brown of Kool & the Gang. Ai was a member of the group for two years, and later in 1999 the group were offered a record label deal. While on her summer holiday in Kagoshima, she performed Monica's "For You I Will" on a local radio station, which led to her being scouted by BMG Japan. She decided to take the offer, and after leaving SX4 and graduating from high school in June 2000, moved to Tokyo and debuted as a musician later in 2000.
