Why not just download and see for yourself? This may be because of my incredibly bad experiences with zines recommending utter shit, perhaps you would care to share a couple of good ones?
The problem: 10,000 bands to download.
With good reviewers: cut down to 10 or 15.
Most of us aren't so fascinated by this we want to dedicate our lives to it.
Regarding magazines, I don't know of any. They may be out there, but last time I looked, I saw plenty of aesthetics and zero substance.
