Recording and Live Sound

Sound On Sound
Music recording magazine offering product reviews and news. UK-based, but it doesn't matter. Very strong website.

Guitar Player
There's a reason this magazine has been around forever. Strong website.

Acoustic Guitar Magazine
Strong website.

For classical players, somewhat academic.

For jazz musicians, although I'm not a jazz musician and learn quite a bit from it.

American Record Guide
America's oldest classical review magazine.

U.K. based, "The world's authority on classical music since 1923."

Classic FM
U.K. based. Almost a pop magazine style of coverage of the classical scene.

The Absolute Sound
Audiophile magazine. Very fun to read. For people who don't question paying $30,000 and more for speakers. Or a couple grand for a few feet of high-end cable.

Wall Street Journal
The Wall Street Journal is now #1 in circulation. It is not just for Wall Street watchers. It is a full paper (even has a sports section). Its arts coverage (articles and reviews) is some of the best in the nation.

New York Times
The Sunday Arts & Leisure Section has been the bible of the New York fine arts scene for years. If you need to keep up with what’s happening in the Big Apple, start here.
