Named for the harried hero of Kafka's The Trial, this Scottish quartet spent the early '80s exploring an appropriately jittery strain of the raucous, groove-filled genre known as post-punk. Neither of the albums they recorded before disbanding made it to the U.S.; thankfully, this long-overdue retrospective, Entomology, includes the choicest cuts from both. Singer Paul Haig's wry wit and guitarist Malcolm Ross' menacing jangle shine on songs like ''Fun 'n' Frenzy'' a lost classic whose title sums up the enduring thrills of Josef K's sound.
