The Principle of Moments, Robert Plant's second solo release, is a good album. A total of eight songs is included. Every one of them is worthwhile and has something to offer. When it comes to the musical style of the disc, some of the tracks are in a pop rock vein, while others are in a progressive pop rock direction. The musicianship is skilled, the songwriting is pleasing, and the production is tight. Plant does a nice job with the vocal duties. Robbie Blunt's guitar playing is proficient. Jezz Woodroffe's keyboard playing is impressive throughout. There are two drummers that play on the album--Phil Collins and Barriemore Barlow. Collins performs on six songs, while Barlow handles two of the others ("Wreckless Love" and "Stranger Here ... Than over There"). Barlow's drumming on the interesting "Wreckless Love" is conspicuous and complex. The two tracks that impress me the most are the memorable and touching "Big Log" (one of my favorite songs) and the engaging "In the Mood." "Big Log" is truly a very good, well-written ballad that I admire; the singing is nice, the guitar work is smooth and unforgettable, and the background vocals are soulful and attractive. The better-than-good "In the Mood" is also a highlight. This gentle, atmospheric track features cool backing vocals and a skillful guitar solo. "Thru' With the Two Step" is another one (containing prominent keyboard playing) that I enjoy that's progressive in nature and ethereal-sounding. The keyboard work is encompassing, lush, and majestic. This tune displays a plaintive and well-played guitar solo, too. The curious and experimental "Stranger Here ... Than over There" contains some ominous-flavored keyboard playing. The CD booklet doesn't include the song lyrics. The disc is just under 39 minutes in duration. The Principle of Moments is consistent and enjoyable.
