By winter of 1995, he began attending various club nights and raves in DC and Baltimore, and making weekly vinyl shopping trips, picking up DJing as a hobby. By 1998, Ransom had a weekly college radio show, as well as consistent bookings at clubs and events in Washington, DC and Baltimore, branching out to national events in 1999.

In 2001, Ransom began working on music production, working on drum'n'bass as a solo artist, as well as collaborating with other local producers, including Matt Nordstrom (of Nadastrom), Rob F & Impulse (of Sinthetix), and Alvin Risk (then of Corrupt Souls, later as Telemetrik).

Harry Ransom has played throughout the U.S., from San Franscisco and Los Angeles, to Miami, Atlanta, Philadelphia, New York and Boston. As of late, his focus is more on production, with several releases on Baltimore-based label Tharsis Records. He remains a constant presence in the Washington, DC music scene, regularly plays at U Street Music Hall, 411 Warehouse, TnT, Rock & Roll Hotel and Jimmy Valentine's Lonely Hearts Club, and booked by promoters such as Eighty Eight Music, 3D Productions, Steez Productions and a few more. He has maintained resident DJ status on Expansion Broadcast since 2006, and in 2013 joined Blisspop as a resident DJ and blog contributor.

Currently he works under the names Harry Ransom and R4NS0M, depending on the style of music produced.
