The Under-Appreciated Rock Band for this month, the Giles Brothers is not properly a band I suppose; they are basically a rhythm section who both sing, consisting of drummer Michael Giles and bass guitarist Peter Giles. However, they also have a recent (2009) compilation CD called The Giles Brothers 1962-1967; and they performed with numerous other bands prior to Giles, Giles and Fripp.
There is a long booklet included with the CD and extensive annotations, including personnel, dates active, the number of “gigs played”, and even several photographs. However, the CD itself is maddening, since the lists of songs that are so carefully laid out on the back cover and in the booklet don’t match up with the songs as they are actually being played. Still, the CD clearly shows the evolution of their music over time, along with the experimentation that would ultimately reach a crescendo with King Crimson. (The Discogs listing for The Giles Brothers 1962-1967 shows the actual sequencing of the 24 tracks on the CD).
