When the ISB broke down, Robin headed for California to team up with the Merry Band, which proved to be a wonderful and powerful combination. Of the 3 studio albums they produced this "Journey's edge" is farthest away from Robin's other work, I think, maybe in a reaction to get away from the ISB as far as he could. The result is really good: the playing is wonderful, each song has its own voice and the overall atmosphere of the album is warm and, if you like, sunny.
We hear hints of things to come in songs like "The tune I hear so well" or "Out on the water" while adaptations like the "Maharajah" are really funny. The musical prowess of the Merry Band comes to the fore in all songs, but especially in songs like "Voices of the Barbary Coast".
The latest release comes with a staggering amount of 10 previously unreleased songs - which is a pleasant surprise, of course. In terms of quality they are all quite good but not on an equal footing with the songs on the original album, I think, so Robin chose well when he decided which songs to put on the album.
In retrospect, I think this album has aged much better than "American Stonehenge", and while it differs greatly from the Merry Band's masterpiece "Glint at the Kindling" it certainly deserves a prominent place in your ISB/Williamson collection.
