Question: What country are the performers of Nova from?

full_context: Document 1: House music: Numerous live performance events dedicated to house music were founded during the course of the decade, including Shambhala Music Festival and major industry sponsored events like Miami's Winter Music Conference. The genre even gained popularity in the Middle East in cities such as Dubai & Abu Dhabi[citation needed] and at events like Creamfields.
Document 2: Tam, de nas nema: Tam, de nas nema (; "Wherever We Aren't") is the debut studio album of the popular Ukrainian rock group Okean Elzy. Svyatoslav Vakarchuk is the lead vocalist and songwriter for most of the lyrics on this album. It was released in 1998 by the Kiev-based record label Lavina Music.
Document 3: A cappella: A cappella [a kapˈpɛlla] (Italian for "in the manner of the chapel") music is specifically group or solo singing without instrumental accompaniment, or a piece intended to be performed in this way. It contrasts with cantata, which is accompanied singing. The term "a cappella" was originally intended to differentiate between Renaissance polyphony and Baroque concertato style. In the 19th century a renewed interest in Renaissance polyphony coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists led to the term coming to mean unaccompanied vocal music. The term is also used, albeit rarely, as a synonym for alla breve.
Document 4: Nova (Rajaton album): Nova is the debut album of Finnish a cappella ensemble Rajaton, released August 14, 2000. It consists of vocal arrangements of folk and contemporary Finnish poetry. The first takes were recorded in June 1999, after Rajaton won the Tampere Vocal Music Festival 1999.
Document 5: Grateful Dead: The Grateful Dead toured constantly throughout their career, playing more than 2,300 concerts. They promoted a sense of community among their fans, who became known as ``Deadheads '', many of whom followed their tours for months or years on end. In their early career, the band also dedicated their time and talents to their community, the Haight - Ashbury area of San Francisco, making available free food, lodging, music, and health care to all. It has been said that the band performed`` more free concerts than any band in the history of music''.
Document 6: Live Earth concert, Antarctica: The Live Earth concert in Antarctica was held at Rothera Research Station, one in a series of Live Earth concerts that took place on July 7, 2007, in all seven continents. The band Nunatak performed as the lone act. Nunatak's performances, though performed in front of only 17 people, were broadcast all over the world. It was the first rock concert ever performed in Antarctica.
Document 7: A cappella: A cappella is gaining popularity among South Asians with the emergence of primarily Hindi-English College groups. The first South Asian a cappella group was Penn Masala, founded in 1996 at the University of Pennsylvania. Co-ed South Asian a cappella groups are also gaining in popularity. The first co-ed south Asian a cappella was Anokha, from the University of Maryland, formed in 2001. Also, Dil se, another co-ed a cappella from UC Berkeley, hosts the "Anahat" competition at the University of California, Berkeley annually. Maize Mirchi, the co-ed a cappella group from the University of Michigan hosts "Sa Re Ga Ma Pella", an annual South Asian a cappella invitational with various groups from the Midwest.
Document 8: A cappella: The Swingle Singers used nonsense words to sound like instruments, but have been known to produce non-verbal versions of musical instruments. Like the other groups, examples of their music can be found on YouTube. Beatboxing, more accurately known as vocal percussion, is a technique used in a cappella music popularized by the hip-hop community, where rap is often performed a cappella also. The advent of vocal percussion added new dimensions to the a cappella genre and has become very prevalent in modern arrangements. Petra Haden used a four-track recorder to produce an a cappella version of The Who Sell Out including the instruments and fake advertisements on her album Petra Haden Sings: The Who Sell Out in 2005. Haden has also released a cappella versions of Journey's "Don't Stop Believin'", The Beach Boys' "God Only Knows" and Michael Jackson's "Thriller". In 2009, Toyota commissioned Haden to perform three songs for television commercials for the third-generation Toyota Prius, including an a cappella version of The Bellamy Brothers' 1970s song "Let Your Love Flow".[citation needed]
Document 9: Aerosmith World Tour 2007: Aerosmith World Tour 2007 (or The Tour Heard 'Round the World) was a concert tour by American hard rock band Aerosmith that saw the band performing outside North America or Japan for the first time in about eight years (since the Nine Lives Tour), and in some countries, the first time in 14 years (since the Get a Grip Tour). As part of the tour, the band also visited some countries for the first time ever, including India, the United Arab Emirates, Latvia, and Estonia.
Document 10: Europalia: Each festival develops a partnership, not only with the chosen country but also with prominent museums, cultural centres and performance halls in Belgium and neighbouring countries. The festival expenses are shared between Belgium and the invited country. Europalia is financially supported by Belgium’s national, regional and community governments and numerous private companies.
Document 11: Elevator Repair Service: ERS has performed in various New York City venues including The Public Theater, New York Theatre Workshop, Performance Space 122, The Performing Garage, HERE Arts Center, The Ontological at St. Mark's Church, The Flea Theater, The Kitchen, and Soho Rep. It has also performed elsewhere in the United States, and in Europe, Australia, and Asia.
Document 12: A cappella: Increased interest in modern a cappella (particularly collegiate a cappella) can be seen in the growth of awards such as the Contemporary A Cappella Recording Awards (overseen by the Contemporary A Cappella Society) and competitions such as the International Championship of Collegiate A Cappella for college groups and the Harmony Sweepstakes for all groups. In December 2009, a new television competition series called The Sing-Off aired on NBC. The show featured eight a cappella groups from the United States and Puerto Rico vying for the prize of $100,000 and a recording contract with Epic Records/Sony Music. The show was judged by Ben Folds, Shawn Stockman, and Nicole Scherzinger and was won by an all-male group from Puerto Rico called Nota. The show returned for a second and third season, won by Committed and Pentatonix, respectively.
Document 13: Rajaton: Rajaton performs primarily in Finland but also tours around Europe and the rest of the world, having performed in over 25 countries.
Document 14: Uusinta Ensemble: Uusinta Ensemble was started in 1998 by the composer Osmo Tapio Räihälä, and in the early years most of its members were composers, such as Max Savikangas, Riikka Talvitie, Kimmo Leppälä and Lauri Toivio. The ensemble has premiered a vast number of Finnish and Nordic composers's music. In recent years, Uusinta's repertoire has widened internationally, much as a result of the ensemble's co-operation with various organizations and festivals. Apart from its native Finland, Uusinta has performed in France, Spain, Denmark, Norway, Sweden, Germany, Austria, Estonia and the United States. Uusinta has premiered over one hundred works by composers of various nationalities. Uusinta’s American debut in New York in April 2014 received very good reviews. Uusinta Ensemble released its first album, "at the edge of time", in 2004.
Document 15: A cappella: Contemporary a cappella includes many vocal groups and bands who add vocal percussion or beatboxing to create a pop/rock/gospel sound, in some cases very similar to bands with instruments. Examples of such professional groups include Straight No Chaser, Pentatonix, The House Jacks, Rockapella, Mosaic, and M-pact. There also remains a strong a cappella presence within Christian music, as some denominations purposefully do not use instruments during worship. Examples of such groups are Take 6, Glad and Acappella. Arrangements of popular music for small a cappella ensembles typically include one voice singing the lead melody, one singing a rhythmic bass line, and the remaining voices contributing chordal or polyphonic accompaniment.
