Back in the mid 2000s, I came across an artist who sported a red jacket like Captain N's and who kind of looked like him. I believe the genre of music was electronic/trance, but maybe it was a related genre. I'm pretty sure he was french. I think there was an animated music video with a car. Kind of dark. Really drawing a blank here, I think I found him on myspace.
Assuming that the "red jacket" is like a "smoking jacket", I think it could be Guy-Manuel of Daft Punk? This fan website talks about a red jacket worn by GM at the time of the band's Discovery album, and has pictures of the fan's recreation of that jacket, which looks like a red leather smoking jacket. The album had a tie-in with an animated film Interstella 5555: The 5tory of the 5ecret 5tar 5ystem.
