If you're interested in jazz, improvised music, the odder modern classical composers and so forth check out Paris Transatlantic. Lots of interesting interviews, album reviews, and other goodies. Its run by Dan Warburton, and some of the material appears in a different form in Signal To Noise magazine, which is well worth checking out if its available at one of your local magazine shops. I think of it as being a US counterpart to The Wire magazine(which is not to be confused with Wired).
