Rivers was somewhat overlooked and definitely undevalued throughout his long career, despite making some fine music in varied settings, key elements from which appear to be currently out of print.
This late outing is a good place to start if you don't know his playing. At 87, there's no sign of weakness in his playing or his ideas. Husky and intimate on tenor, dryly acerbic on flute, and suitably oriental on soprano, Rivers here is supported elegantly here by his band. The addition of vibes is very welcome. This music flits between being in the tradition and just beyond it. The recording is good and satisfyingly close.
