Yeah it's note necessarily *weird* in the Frank Zappa vein but just music that is often hard to pin into one genre.
I started calling a style of music 'ambient organic' including all manner of folky, worldy, mellow non-electronic sounds, not just jazz, but the jazz section is growing and growing.
Yes I've got plenty of flute, piano, guitar, chamber, marimba, sitar, oud-based stuff in my ambient organic list! Little bit of brass too if it's mellow enough, it's in!
