The Upsessions are an early reggae-styled band from Haarlem and Amsterdam. They were founded in 2005 by trombone player Giel (former member of Amsterdam-based ska band De Hardheid) and lead vocalist Boss (former bassplayer of Rude Rich and The High Notes). After playing Holland's biggest ska festival, Dutchska (along side big names such as The Moon Invaders, Intensified and Winston Francis), they went international, playing in France, Switzerland, Belgium and several festivals (This-Is-Ska and Summer Safari) in Germany.
