"Dial S..." is not one of Clark's more outstanding albums. At least, it always struck me that most of the compositions are relatively uninspired, and give me the impression that this is one record that he simply cranked out for a quick paycheck. Listening to it again recently has not caused me to change this opinion substantially. The first two tracks strike me as perfectly decent, but after that the rest of the album still registers a bit on the dull side, at least compared to his other work. So I can understand your reaction.
All of which causes me to ask, for the thousandth time: When are they going to RVG Leapin' and Lopin'?
