Cat Stevens was clearly one of the most brilliant songwriters of the last century. Becomes clear when you hear the songs again after many years - a classic follows the other. The quality of the CD is fine, with old material so you can hardly rauskitzeln. The songs can take anything a little shaky sound and timeless (except for the very old songs in 60's Sound) and wonderful. The best the pieces that make do with voice and guitar or piano - more is needed. The biography in the booklet is also very nicely done, but in English. Highly Recommended.
