I found this article from Outsider Online.

As Johnson explains it, Kelly Slater started riding new high-performance boards in the 1990s that were ridiculously thin and narrow. Slater, who’s known as”the Freak” for his extraordinary surfing abilities, could ride these boards with flair, but lots of other surfers couldn’t. Then the fish and other retro styles made a comeback. “You jump on there and suddenly you can glide again,” Johnson says. “I think about this in terms of music or anything: Sometimes things progress to the point that it’s not really progressing anymore. You get to this dead end, where you need to look back.”
