It wasn’t until I read about it in the January/February issue of the British world-music magazine Songlines that I learned that the latest installment of the invaluable Rough Guide to World Music had recently been published. The second volume of the book’s third edition—focusing on Europe, Asia, and the Pacific—came out in the U.S. on December 21, perfect timing for getting lost in the holiday shuffle. The first volume, on Africa and the Middle East, came out in October 2006, so the wait has been pretty long for the second.
