In chemistry, a solution is a homogeneous mixture composed of only one phase. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. The solvent does the dissolving. The solution more or less takes on the characteristics of the solvent including its phase, and the solvent is commonly the major fraction of the mixture. The concentration of a solute in a solution is a measure of how much of that solute is dissolved in the solvent.

Homogeneous means that the components of the mixture form a single phase. The properties of the mixture (such as concentration, temperature, and density) can be uniformly distributed through the volume but only in absence of diffusion phenomena or after their completion. Usually, the substance present in the greatest amount is considered the solvent. Solvents can be gases, liquids, or solids. One or more components present in the solution other than the solvent are called solutes. The solution has the same physical state as the solvent.

The Raconteurs /ˌrækɒnˈtɜrz/ (also known as The Saboteurs in Australia) is an American rock band that was formed in Detroit, Michigan, featuring four members known for other musical projects: Jack White (of The White Stripes and The Dead Weather), Brendan Benson (solo), Jack Lawrence (of The Greenhornes, Blanche and The Dead Weather), and Patrick Keeler (also of The Greenhornes).

The band is based in Nashville, Tennessee. According to the band's official website, "The seed was sown in an attic in the middle of a hot summer when friends Jack White and Brendan Benson got together and wrote a song that truly inspired them. This song was 'Steady, As She Goes' and the inspiration led to the creation of a full band with the addition of Lawrence and Keeler." The band came together in Detroit during 2005 and recorded when time allowed for the remainder of the year. Due to the various members' success in other bands, they were quickly dubbed a supergroup. The band, however, asserted they were not, saying that the term implies something pre-planned or temporary, whereas they are actually "a new band made up of old friends."
