Jon Georg Balke (born 7 June 1955 at Furnes, Ringsaker, Norway) is a Norwegian jazz pianist and composer currently known for his Magnetic North Orchestra. He is the younger brother of saxophonist Erik Balke.

Balke started playing classical piano, but switched to blues at 12, though today he performs within several genres. At the age of 18 he joined Arild Andersen's quartet. By the mid-1980s he worked on his own and would become one of Norway's leading jazz composers. He was active in the groups of Radka Toneff and in the Afrofusion group E´olén before joining Oslo 13 and Masqualero in the early 1980s. From 1989 he focused on his own projects, such as JøKleBa (with Audun Kleive and Per Jørgensen) and the still existing Magnetic North Orchestra for which he composed the commissioned work Il Cenoneat to Vossajazz 1992.

Balke formed the percussion group Batagraf in 2002, and created the concept work Siwan with singer Amina Alaoui in 2007. He is also the creator of a series of multimedia concerts at Vossajazz festival, labeled Ekstremjazz. The concerts involve various practitioners of extreme sports, such as parachuting, paragliding, hanggliding, and bmx biking. In 2012 he was "Artist in residence" at Moldejazz.[6]In 2016 he launched the solo piano concept Warp, with a subtle use of live electronics accompanying the grand piano in live performances.

Bugge Wesseltoft is a man who likes to push the envelope and he is well-known as one of the most innovative jazz pianists today. His collaborations with DJs like Henrik Schwarz and his experiments with electronic music have made him a name far beyond the contemporary jazz scene. At the beginning of the 90s Wesseltoft – surrounded by musicians like Nils Petter Molvær and Eivind Aarset – started out in Norway's progressive jazz scene to become one of the leading figures in a radical new approach to jazz. Since then he has continuously weaved elements of house, techno, ambient and noise into jazz and some free improvisations for his project "New Conceptions of Jazz". But for all that, Wesseltoft's lyrical and melodious playing was always very tangible. In working for ACT he essentially became famous for this facet of his artistic personality: The 1997 solo Christmas album "It's Snowing On My Piano" presents him in a very intimate acoustic setting. In 2012 the release of the sequel to this very special work "Last Spring" continued. In collaboration with classical violinist Henning Kraggerud, Wesseltoft once again returns to Norwegian lore, but this time adapts classical compositions – for example by Edvard Grieg – to create an album of minimalistic meditations.
