Wavelength essentially picks up where A Period of Transition left off, offering a focused, full-bodied alternative to that record's warmly fuzzy lack of direction. Like that album, it's hardly a major entry in his catalog, but there are signs that Morrison is finding his footing for his latter-day voice. Again, the primary appeal of this record is its atmosphere, a charmingly relaxed outing, high on mildly swinging mid-tempo numbers and round, welcoming ballads. Surely, an album of subtle pleasures like this is primarily for the converted, but once you're there, it's hard not to resist Wavelength.
