The festival was set up as the Rheinknie Session in 1985, with the five concerts of the first instalment of the festival in May 1986, including performances by
Oscar Peterson,
Albert Collins and
Koko Taylor. The second year's edition included shows by
Fats Domino and
Buddy Guy.
Regional establishment In 1988
Miles Davis agreed to perform at the festival. Subsequently, the festival was first acknowledged outside of north-western Switzerland. Names such as
Dizzy Gillespie,
Michel Petrucciani and
Herbie Hancock followed and Claude Nobs from
Montreux Jazz Festival joined as a member of the patrons committee. In its first ten years the festival focussed on continuous growth. By gradually integrating musical styles such as
world music,
soul and
funk after 1995, it proved possible to approach a younger audience.
National take-off In 1997 the festival management decided to revamp the festival's content as well as its look and the festival's image was rejuvenated with greater importance attached to the attraction and driving power of international performers. The club style seating arrangement, the combination of acts and the opportunity to experience big names in an intimate atmosphere have become trademarks. Embracing this vision, presenting sponsor AVO Cigars, part of Oettinger
Davidoff, agreed to a growth-orientated sponsorship deal, with the festival becoming known as the AVO SESSION Basel. In 2013, the festival acquired sponsorship from a Swiss insurance company called
Bâloise, changing the name of the event to Baloise Session, with sponsorship in place for the ten-night event till at least 2025. ==Performances of note==
