A lot of artists run with duplicate names. You could just add a location/descriptive to your name i.e. D-Rev USA, D-Rev NYC... Many people do it and I've heard that's acceptable under US law.
However, if it's a company who has trademarked the name, you may have difficulty... Especially if they operate in the music industry. I'm sure there's a trademark check in the USA, you can see what categories the trademark is registered under (i.e. the industry)...
Bare in mind, I'm not a lawyer. There is a possibility I'm wrong. Read through your governments support documents, there should be an official website on the topic of copyrights, trademarks, patents, etc.
Hope I've helped.
