Sebastian "Kebu" Teir is a Finnish keyboard player, arranger and composer. Teir's musical career began in 1999, playing keyboards in the progressive rock band Prime Mover, with whom he released three albums and a demo. He has also played keyboards in the progressive metal band Kouzin Bedlam. In 2008 he joined the soul/funk band Vinyl Jam on their single Test of Wind (2008) where he played organ, Moog synthesizer, and Hohner Clavinet. The band recorded their vinyls with the principle that everything in the signal chain had to be analog. This inspired Teir to make his debut album in a similar way, with the addition of using analog synthesizers as the only instruments. Teir recorded his debut solo album under the pseudonym Kebu in 2012, Jupiter and Back, which is inspired by the electronic music of world-renowned composers who create music on analog synthesizers, e.g. Jean-Michel Jarre, Jan Hammer, Vangelis and Giorgio Moroder.
