Hardfloor is a German electronic music duo, consisting of Oliver Bondzio and Ramon Zenker. Their most famous track is "Acperience 1" and chosen by Feargal Sharkey as one of his 'Inheritance Tracks' when interviewed on UK's BBC Radio 4.

"Yé ké yé ké" is a song by Guinean recording artist Mory Kanté. It was released in 1987 as a single from his third studio album, Akwaba Beach. The song became an international hit; it was one of Africa's best-ever selling hits as well as being a European number one in 1988, making it the first ever African single to sell over one million copies. The song was a top five hit in France, Switzerland, Germany and the Netherlands, where it topped the chart for two weeks. A remix, the "Afro Acid Mix" was especially made for UK release, where it reached No. 25. In 1994, German techno duo Hardfloor remixed the song and released this new version with moderate success. A Bollywood song, "Tamma Tamma Loge", also used the music of the song.
