Sebastian York is the pseudonym of Rob Shapiro.
Sure?
His bio is completely different to York; who claims to be British.
Of course, that could all be fantasy.
Rob Shapiro
Rob Shapiro got his professional start as an entertainer doing stand-up in Minneapolis while still in high school (the Children's Theatre Company & School of Minneapolis). As a voice-over artist, he can be heard narrating such audiobooks as the bestselling The Information: A History, a Theory, a Flood by James Gleick, Frank: The Voice by James Kaplan, and the fantasy noir Low Town by Daniel Polansky. He performed several seasons of radio comedy on Minneapolis Public Radio and voiced the titular lion in Leo the Lion. Rob is also a musician and composer; with his critically acclaimed band, Populuxe, he has released two CDs—A Foggy Day in Brooklyn and Deep in an American Evening . . .—and the EP, Daphne. He is one half of the Velvet Collar, who released their first record, Double Standard, an unlikely collection of cover songs by the Stooges, Hoagy Carmichael, and the Gershwin Brothers, among others, in 2011. Finally, Rob is a business consultant and software system designer, specializing in desktop publishing and workflow efficiency, with clients and implemented systems spanning the globe.
