Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers. Like all other electromagnetic waves, they travel at the speed of light. Naturally occurring radio waves are made by lightning, or by astronomical objects. Artificially generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, satellite communication, computer networks and innumerable other applications. Different frequencies of radio waves have different propagation characteristics in the Earth's atmosphere; long waves may cover a part of the Earth very consistently, shorter waves can reflect off the ionosphere and travel around the world, and much shorter wavelengths bend or reflect very little and travel on a line of sight.

Radio waves were first predicted by mathematical work done in 1867 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory. Many inventions followed, making the use of radio waves to transfer information through space.

George Roger Waters (born 6 September 1943) is an English musician, singer-songwriter and composer. He was a founder member of the progressive rock band Pink Floyd, serving as bassist and co-lead vocalist. Following the departure of bandmate Syd Barrett in 1968, Waters became the band's lyricist, principal songwriter and conceptual leader. The band subsequently achieved worldwide success in the 1970s with the concept albums The Dark Side of the Moon, Wish You Were Here, Animals and The Wall. Although Waters' primary instrument in Pink Floyd was the bass guitar, he also experimented with synthesisers and tape loops and played rhythm guitars in recordings and in concerts. Amid creative differences within the group, Waters left Pink Floyd in 1985 and began a legal battle with the remaining members over their future use of the group's name and material. The dispute was settled out of court in 1987, and nearly eighteen years passed before he performed with Pink Floyd again. It is estimated that as of 2010, the group have sold over 200 million albums worldwide, including 74.5 million units sold in the United States.

Eli Young Band is an American country music band based in Denton, Texas. The band is composed of Mike Eli (vocals, guitar), James Young (guitar), Jon Jones (bass guitar), and Chris Thompson (drums). They released their self-titled debut album in 2002, followed by the Carnival records release Level in 2005. Their third album, Jet Black & Jealous, was released in 2008 by Universal South Records. A second major-label album, Life at Best, was released in 2011 by Republic Nashville; it includes their first #1 hit, "Crazy Girl".

Mike Eli and James Young met each at the University of North Texas when they became dorm roommates their freshman year. They played guitar and eventually began writing and singing songs together; they formed the acoustic duo, Eli & Young, while attending the University of North Texas. Chris Thompson and Jon Jones joined them later on and they became the Eli Young Band.

They released their first album in 2002, self-titled "Eli Young Band". In 2005 they released "Level" on Carnival Records and opened shows for Miranda Lambert. National exposure on CMT and GAC helped them begin to build a following well outside of their touring base. They sold as many as 2,000 tickets a night in multiple markets. In late 2006 they released Eli Young Band Live At the Jolly Fox located in Huntsville, Texas. Early in 2007, they signed a management deal with George Couri and C3 Management. Their plans included a rigorous tour schedule and key opening spots with Pat Green, Robert Earl Keen, and Jack Ingram, as well as a spot on the 2007 Austin City Limits Music Festival.
