The sky, also known as the celestial dome, commonly refers to everything that lies a certain distance above the surface of Earth, including the atmosphere and the rest of outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an imaginary dome where the sun, stars, planets, and the moon are seen to be traveling. The celestial sphere is divided into regions called constellations. Usually, the term sky is used from the point of view of the Earth's surface. However, the exact meaning of the term can vary; in some cases, the sky is defined as only the denser portions of the atmosphere, for example.

During daylight, the sky appears to be blue because air scatters blue sunlight more than it scatters red. At night, the sky appears to be a mostly dark surface or region scattered with stars. During the day, the Sun can be seen in the sky, unless obscured by clouds. In the night sky (and to some extent during the day) the moon, planets and stars are visible in the sky. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae. Lightning and precipitation can also be seen in the sky during storms. Birds, insects, aircraft, and kites are often considered to fly in the sky. As a result of human activities, smog during the day and light pollution during the night are often seen above large cities.

The arts are a vast subdivision of culture, composed of many endeavors (or artforms) united by their employment of the human creative impulse. The term implies a broader range of disciplines than "art", which in modern usage usually refers only to the visual arts. The other major constituents of the arts are the literary arts, more often called literature – including poetry, novels and short stories, among others – and the performing arts, among them music, dance, theatre, opera and film. Literary arts and creative writing are actually interchangeable terms. These divisions are by no means absolute as there are artforms which combine a visual element with performance (e.g. film) and the written word (e.g. comics). This list is by no means comprehensive, but only meant to introduce the concept of the arts.

Whether or not a form of creative endeavor can be considered one of "the arts" can be contentious due to the cultural values attached in Western culture to the term "art", which can imply that it is a field elevated above popular culture.

Robert Anthony Plant, CBE (born 20 August 1948) is an English singer and songwriter best known as the vocalist and lyricist of the iconic rock band Led Zeppelin. He has also had a successful solo career. In 2007, Plant released Raising Sand, an album produced by T-Bone Burnett with American bluegrass soprano Alison Krauss, which won the 2009 Grammy Award for Album of the Year at the 51st Grammy Awards.

With a career spanning more than 40 years, Plant is regarded as one of the most significant singers in the history of rock music, and has influenced contemporaries and later singers such as Freddie Mercury and Axl Rose. In 2006, heavy metal magazine Hit Parader named Plant the "Greatest Metal Vocalist of All-Time". In 2009, Plant was voted "the greatest voice in rock" in a poll conducted by Planet Rock. In 2011, a Rolling Stone readers' pick placed Plant in first place of the magazine's "Best Lead Singers of All Time".

Plant was born in the Black Country town of West Bromwich (then in Staffordshire now in West Midlands) to parents Robert C. who worked as a civil engineer and Annie C. (Cain) Plant, but grew up in Kidderminster, in Worcestershire. Plant gained an interest in singing and rock and roll music at an early age.
