Jonathan Axelsson was born in Sweden, and got in touch with music very early in life since both his father and grandfather were musicians. As a young boy he started playing drums, and then continued with piano lessons.

In the mid 90´s he discovered a new type of music that would change his life forever. The music he heard was calld deephouse, and struck Jonathans heart immediately. He now started to produce music in a more serious matter and in 1997 he got in touch with Johan Bacto, which later formed the label PlackTown Sounds. Jonathan was now known as Ronin, and made alot of releases on the PlackTown Sounds imprint. With alot of great feedback from radiostations, magazines, DJ´s and even television, Ronin continued on the path of sensual, moody deephouse.

His music was reaching out to the world, and in the year of 2001 he released a mini LP on Chris Grays label, Deep4Life in Chicago. Chris gave Jonathan his second artist name J. Axel, and he was now focusing on vocal deep-house, and he started working with the talanted vocalist Astrid Suryanto. He still produced instrumental deephouse as Ronin (for example in 2002 he made a release on the label Driftwood from The Timewriter & Terry Lee Brown Junior). Since today, Jonathan has released on various labels like Deep4Life, Plastic City, Statra, Primary, Blacktown and contributed with music on many compilations as well as DJing in alot of clubs over the years. His releases and DJ-sets have always been criticaly acclaimd, and its now a fact that he will keep on delivering music with precence and luxury, which touches mind, body and soul.
