It would be surprising if it were a language issue, given Bach speaks accented english much more rapidly than the host speaking mostly unaccented english. It seems received or an personality/attitude thing, or maybe it's a substance use issue. Anyway, Bach is interesting enough I'm putting up with it, but I rarely feel so irritated and resentful of a person, so if someone else is repelled by it, stick with the podcast as Bach makes it worth while.
