A cajón (Spanish pronunciation: [kaˈxon], "crate," "drawer," or "box") is a box-shaped percussion instrument originally from Peru, played by slapping the front face (generally thin plywood) with the hands.

The cajón is the most widely used Afro-Peruvian musical instrument since the late 18th century.

Slaves of west and central African origin in the Americas, specifically Peru, are considered to be the source of the cajón drum; though the instrument is common in musical performance throughout the Americas.

The cajón was most likely developed in coastal Peru during the early 19th century or before, where it is associated with several Afro-Peruvian genres. The instrument reached a peak in popularity by 1850, and by the end of the 19th century cajón players were experimenting with the design of the instrument by bending some of the planks in the cajón's body to alter the instrument's patterns of sound vibration.

Knowing that the cajón comes from slave musicians in the Spanish colonial Americas, there are two complementary origin theories for the instrument. It is possible that the drum is a direct descendant of a number of boxlike musical instruments from west and central Africa, especially Angola, and the Antilles. These instruments were adapted by Peruvian slaves from the Spanish shipping crates at their disposal. In port cities like Matanzas, Cuba they used cod-fish shipping crates. Elsewhere, small dresser drawers became instruments.

The Basics ( /ˈbæzɪtʃ/ BAZZ-ich) are a three-piece band from Melbourne, Australia, formed by Wally De Backer and Kris Schroeder in 2002. Their style has been described as anything from 'indie-pop' to 'rock'n'roll' to 'pop-rock', though their records show they span a wide range of genres, including reggae, ska, country, and electro-pop. They are "recognised as one of Australia's hardest-working bands".

With close to 1000 shows in their ten-year career, their live performances are well-known for their sense of humour and energy.

The Basics were formed after Kris met Wally at a party in Melbourne. The event was to see off the young aspiring producer, who was about to depart for Los Angeles, and together with a number of musician friends, the two jammed on some blues-rock standards. Later that night, they bonded over a mutual love of The Beatles, 70s and 80s cartoon theme songs and old Sierra adventure games.

Initially, they played around Melbourne as an acoustic guitar/drums combo, starting at The Opposition in Frankston and the House of Fools in Footscray, where in late 2002 they met Michael Hubbard and later invited him to join them on electric guitar. Though lacking any real experience with the instrument, Kris willingly purchased his first bass guitar, and the trio was born. During this time, the group start performing songs with more complicated three-part harmony.
