IN: 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".

Where was he from ?

OUT: 

input: By the late 1980s, the band's popularity was starting to decline. Alan Gratzer left in September 1988 after he decided to retire from music to open a restaurant. In early 1989, Gary Richrath quit after tensions between him and Kevin Cronin boiled over. Cronin had been playing in The Strolling Dudes, a jazz ensemble that included jazz trumpet player Rick Braun (who had co-written the abovementioned "Here With Me" with Cronin), Miles Joseph on lead guitar and Graham Lear on drums. Lear had already been invited to join REO in September 1988 as Gratzer's successor and Joseph was brought in as a temporary stand-in for Richrath. Back up singers Carla Day and Melanie Jackson were also added. This lineup did only one show, on January 7, 1989 in Vina del Mar, Chile, where it won the award for best group at the city's annual International Song Festival. After that, Miles Joseph and the back up singers were dropped in favor of former Ted Nugent guitarist Dave Amato (who was brought aboard in May 1989) and keyboardist/songwriter/producer Jesse Harms.  The 1990 release The Earth, a Small Man, His Dog and a Chicken, with Bryan Hitt (formerly of Wang Chung) on drums, was a commercial disappointment. The album produced only one, and - to date - the band's last Billboard Hot 100 single, "Love Is a Rock," which peaked at #65. Harms, disenchanted by the album's failure, left the group in early 1991.  Shortly after his departure, Richrath assembled former members of the Midwestern band Vancouver to form a namesake band, Richrath. After touring for several years, the Richrath band released Only the Strong Survive in 1992 on the GNP Crescendo label. Richrath (the band) continued to perform for several years before disbanding in the late 1990s. In September 1998, Gary Richrath briefly joined REO onstage at the County Fair in Los Angeles to play on band's encore song, "157 Riverside Avenue". He then joined REO once again in Los Angeles in May 2000 for the same encore but no serious plans for a reunion ever materialized.  Having lost their recording contract with Epic, REO Speedwagon ended up releasing Building the Bridge (1996) on the Priority/Rhythm Safari label. When that label went bankrupt, the album was released on Castle Records, which also experienced financial troubles. REO Speedwagon ultimately self-financed this effort, which failed to chart. The title track did make R&R's AC Top 30 chart.
