The one I recommend is 'The Wire'. It's not strictly IDM, but covers new
and interesting music, and is not full of bullshit like the dance music
magazines are. Every now and then it has really interesting articles, like
Autechre and Panasonic who have both been the main articles.
There's also Magic Feet and Jockey Slut, but I don't know anything about
these 'cos I aint read 'em.
