40 Lohh is the stage name of Chris Gibson, who is currently based in Kennesaw, Georgia, though he originally hails from Manchester, New Hampshire. He has several videos available for listening on Youtube.
His emphasis seems to be on hooks, but while listening a lot of the music seemed like it would work better as background, like he might do well scoring commercials or television.
There was an interesting mix of sources sampled, including jingles ("I'm Lovin It"), theme songs ("Everybody Hates Chris"), and contemporary songs ("Break Even").
I thought there might be a connection between how well I liked the original and how well I liked the 40 Lohh version, because I enjoyed his version of "Somebody That I Used To Know", and the Gotye version annoys me to no end. However, I am not particularly fond of Tom Jones' "She's A Lady", and I still found the remix jarring.
My favorite track was "Madness", which may be completely original, or just pulling from material that is unfamiliar to me. It is haunting, and builds intensity nicely.
