Doc Brown

Ben Mark Hammond, known professionally as Doc Brown, is a British rapper and songwriter. He has released several albums and EPs, showcasing his unique blend of hip-hop and energetic live performances.

I was able to verify that Doc Brown is indeed a real artist, and the titles "Concurrence", "Flashback", and "Last Chance to be Crazy" are associated with him, although I couldn't confirm if they are among his most recent releases.
