"In Salah", singled out in reviews I've read for particular attention, sounds to me like a dead ringer for "A Night In Tunisia". The album as a whole is very much of its time; pleasant enough in the background and is nicely short at a touch over half an hour.
Once again, as I have found with albums of a similar age by Fats Domino and Elvis Presley, what this album represents is historical value; it was ground-breaking; it now is run-of-the-mill. If it took a white man to impart a "respectability" that was perceived to be lacking in the music performed by black musicians for a decade or two, then great. But on its own merits, in the 21st century, it's distinctly unimpressive.
