Born in South Korea and raised in America by way of Baltimore, MD, A-Class found hip-hop in the early 90s by listening to dubbed cassettes and jumping in neighborhood and schoolyard ciphers. By 2004 A-Class had thrust himself on to the battle scene, having made two appearances on Baltimore’s own 92.3Q Jams’ Tuesday Night Fights. In 2007, Class dropped his debut project titled "Motive Response" on Brake Fast Records. A-Class has since received considerable press in Baltimore city papers for wins in battles around the DMV including the 2008 Scribble Jam pre-lims and the Baltimore Masters competition. The Baltimore Examiner has described A-Class as having as "sick word play, dynamic cadence, great stage presence, and a sharp mind for insults" while the City Paper observed that "it'd be boring to watch him win all the time if he wasn't such a talented performer".

In 2009, he was featured on Tom Delay’s concept album "Cases", penning the lead single, "Case I Find".

Most recently A-Class has become a top tier competitor on Grind Time Now, the world’s #1 rap battle league.

His 2nd EP titled "Deathsuit" is set to drop on Brake Fast Records in early 2012.

Through all the politics the art form has attached to it, A-Class separates himself from the pack with a fresh style and realistic outlook on what’s going on. "I can’t feel all that mess on the radio and from all the others. Heads get caught up trying to be what’s excepted or what they perceive to be hot at the time but years later their trend is dead. Just stay timeless" (A-Class Real Quotes, 2011).
