Marshall Altman began his music career in the mid 90's fronting the band Farmer, which was subsequently signed to Aware Records. After several US tours, Marshall found himself drawn more to developing and recording new artists than pursuing his own recording career, and after a series of recordings with Citizen Cope (that resulted in Citizen Cope signing to Capitol Records), Marshall seamlessly transitioned into A&R. Despite his successes inside the label system, the desire for unbridled creativity was too great and in 2005, he left Columbia Records and embarked on a full time career as a writer/producer.

In the first 5 years of this new career, he has firmly established himself as one of very few writer/producers who can work across virtually all genre's of music with acclaimed albums made in the mainstream pop, singer/songwriter, country, Christian, metal and indie worlds. Known for defining the emotional currency of the artists he has worked with, his producer credits include: Matt Nathanson (two platinum singles), Marc Broussard, Elliot Yamin, Kate Voegele (platinum single), William Fitzsimmons (itunes singer/songwriter album of the year (US and Australia), Walker Hayes, Rosi Golan, Brooke Frasier, Adema, Matt Wertz, Trevor Hall, Caitlin Crosby, Kim Caldwell, and Tom Morello and others.

Marshall is currently enjoying a top 10 hit in the UK of his co-write "Parachute" performed by Cheryl Cole. He is in the midst of producing Matt Nathanson's follow up album for Vanguard, as well as preparing for upcoming productions with Natasha Bedingfield and Gabe Dixon.
