Being into things before they're cool: George Shearing

I don't know why, but this "year in review" story made little tickly fingers run up my spine.

"Jack Kerouac was into George Shearing before it was cool to be into George Shearing (or into Jack Kerouac, for that matter) . . . . The squares still didn't get it, man."

What are you into that's not cool (yet)?
