Sir Reginald Pikedevant, Esquire is one of the world's premier purveyors of Steampunk Chap Hop.
What is Chap Hop? Imagine rap music, were it written and performed by an upper-class British twit. In Sir Reginald's case, he combines the rhymes, delivered in Received Pronunciation, with the sounds of the Victorian music-hall, Barbershop quartets, and instruments both modern and vintage, both mundane and unusual.
And what is Steampunk? Well, that's a complex question. It started as a literary genre: modern authors writing stories set in the Age of Steam, positing modern ideas realised through Victorian technology (mechanical computers, and so forth). From there, it spawned a fandom encomapassing many artistic forms. (Still confused? Perhaps Sir Reginald's debut music video will clear it up!)
