For music business stuff, I read "Gig Magazine". This magazine is totally out of the "folk, traditional" genre and that is one reason I enjoy getting it. There are articles about being in a band, sound reinforcement, singing technique, guitar chords for songs, touring clubs. Although, I sometimes don't find a lot in every issue, I am often surprised by the gems that I do find.Plus, there is something very satisfying about getting an issue of "Gig" with a wild rocker on the front at the same time I get my Science News, and my traditional mags.
