Up until a few days ago, I was quite unaware of a battle between rival rappers taking place across the pond. Maybe that's because the battle's being waged so... politely.
This war of words is a bit more (okay, a LOT more) gentlemanly than your typical hip-hop dissyfit dustup, because the rappers in question aren't strictly in the hip-hop camp, but rather a humorous offshoot called chap-hop, tea-sipping Victorian-style steampunks who would rather rap about their knowledge of cricket and maybe challenge the other guy to a bout of Queensbury Rules boxing.
The two with the beef are called Professor Elemental, clad in Victorian-explorer garb complete with pith helmet, and Mr. B. The Gentleman Rhymer, a bit more modern and dandy-ish, and an ever-present banjolele.
Check them out, good sir or madam! Pip pip!
