Not exactly a jazz magazine, but it'll cover music of relevant interest to many here.

(I believe Brian brought this up on another thread.)

It's a new magazine covering electronic and innovative
music of all kinds--so yes, you'll see erstwhile releases covered, as well as such groups that have been popular among listeners here like Supersilent and Fennesz.

you can subscribe at their website or maybe find a copy on a
newstand.
