There are good things to be found these days with music that dwells within the interstices of categories. Take Joy Mega and their Forever is Inside of You (New Atlantis). It's the brainchild of bassist-vocalist-composer Jason Ajemian, who straddles the rock and new music/jazz camps in various very good ways and decided to combine rock/alt song and avant freedom with this group.
It's a pretty heavy hitting lineup: Jason on bass, Chad Taylor, drums, Matt Bauder, tenor/reeds, Mary Halvorson, electric guitar, Jessica Pavone, violin. Those who know the scene will recognize that this is a group of some of the most innovative improvisers around today, all bandleaders in their own right and major proponents on their instruments.
Well, that's the specs, so to speak. What you get music-wise is the successful results of the categoric experimentation. Jason's voice is in the raw, direct court and his songs bounce against the avant improv in unexpected, always interesting, and very creative ways.
If you don't give a hoot about categories and thrive on the new however it conjoins, listen to this one a bunch of times. It's seriously different.
