Question: Information:  - The Republic of Iceland, "Lýðveldið Ísland" in Icelandic, is a Nordic island country in the North Atlantic Ocean. It has a population of and an area of , making it the most sparsely populated country in Europe. The capital and largest city is Reykjavík. Reykjavík and the surrounding areas in the southwest of the country are home to over two-thirds of the population. Iceland is volcanically and geologically active. The interior consists of a plateau characterised by sand and lava fields, mountains and glaciers, while many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence still keeps summers chilly, with most of the archipelago having a tundra climate.  - Jón Þór "Jónsi" Birgisson (born 23 April 1975) is the guitarist and vocalist for the Icelandic post-rock band Sigur Rós. He is known for his use of a cello bow on guitar and his falsetto or countertenor voice. He is blind in his right eye from birth as a result of a broken optic nerve from the brain. He is openly gay. Apart from Sigur Rós, Jónsi also performs together with his partner Alex Somers as an art collaboration called Jónsi & Alex. They released their self-titled first book in November 2006, which was an embossed hardcover limited to 1000 copies, along with their first album, "Riceboy Sleeps", in July 2009.  On 1 December 2009, Jónsi's official website, jonsi.com, was launched in anticipation of his debut solo album, "Go", which was released the week of 5 April 2010. After the release of the album, Jónsi promptly started a worldwide tour across North America and Europe, featuring songs from the album plus a few other selections, planning to tour from March to September.  - A lava field, also called a lava plain or lava bed, is a large expanse of nearly flat-lying lava flows. Such features are generally composed of highly fluid basalt lava, and can extend for tens or even hundreds of miles across the underlying terrain. The extent of large lava fields is most readily grasped from the air or in satellite photos, where their typically dark, nearly black color contrasts sharply with the rest of the landscape. According to the US Geological Survey, monogenetic volcanic fields are collections of cinder cones, and/or Maar vents and associated lava flows and pyroclastic deposits. Sometimes a stratovolcano is at the center of the field, as at the San Francisco Volcanic Field in Arizona. Monogenetic volcano fields have systematic growth patterns that suggest they represent single magmatic systems in the same way that stratovolcanoes do, but monogenetic volcanoes grow laterally rather than vertically (Wood and Shoan, 1984). Detailed mapping indicates that some cinder cones in monogenetic fields (e.g., Cima, California, and Timber Mountain Volcanic Field, Nevada) may have had multiple eruptions separated by tens to hundreds of thousands of years (Wells, et al., 1989). Thus, some monogenetic cones may actually be polygenetic. This possibility differs from observations of historic eruptions (Wood, 1979), and is physically difficult to understand because cinder cone conduits are narrow and must solidify within a few years of eruption. Nonetheless, such multiple eruptions appear to have happened at least twice: Other cinder cones need to be closely reexamined.  - Riceboy Sleeps is the debut studio album by ambient duo Jónsi & Alex, released on 20 July 2009. The album is an artistic collaboration between Sigur Rós vocalist Jón Þór Birgisson and partner Alex Somers which features acoustic instrumental music alongside a string quartet, Amiina, and the Kópavogsdætur Choir.  - Alex Somers (born 7 March 1984) is an American visual artist and musician from Baltimore, Maryland.
