Jazz & Indie "Movement" - Harvard Rocker
I'm not going to deny that there are more jazz musicians today looking to rock as source material either as covers (Mehldau) or their production values (Bad Plus), but I don't really know if it qualifies as a movement just now. Brad's trio is about as mainstream as it gets, (I mean that in a good way, not as a pejorative), it's always jazz, just sometimes they're playing a Radiohead tune.
I think The Bad Plus might fit that concept of jazz-indie rock fusion a little better, since their sonic aesthetic seems to be as much from the rock world as the jazz world, though I'm not sure if one group a movement makes. Or even two for that matter.
Add that to the idea that this is nothing new (jazz and rock have a long history together, dating back to the mid 60's). Even at the height of the neo-classic jazz movement of the 80's and 90's there were guys like John Zorn who were doing the same sort of thing (though perhaps without the effective promotion that Sony has lavished on TBP.
If anything, I think this supposed movement is more about marketing than music. The marketing (see picture for exhibit 1) people are always looking for ways to market jazz to new younger listeners, and are always looking for the next big thing.
