Montreal-based musician Martin K. Petersen was born and raised in Denmark. He started out playing xylophone in the school band and later switched to keyboards. Having no instrument at home, Martin got up and went to school early every morning to practice on the piano before class started. Later he took an afternoon job as bike courier so he could rent a keyboard and practice at home.

Over the years Martin performed in several musicals at Svendborg Theatre including Godspell and Joseph and the Amazing Technicolor Dreamcoat, and he played keyboards in the Danish rock/blues band The Overheads.

In 2000 a work opportunity caused Martin to move to Ottawa in Canada. Once settled on Canadian soil Martin bought a real Hammond and started pursuing his passion for jazz organ, listening to players such as Jimmy McGriff, Dr. Lonnie Smith, Jack McDuff and Jimmy Smith. To this day Martin's principal source of inspiration is the early Blue Note organ recordings.

Martin is also known as the world's first Hammond cyclist.
