Here's where they start showing off. If "Lost in the Supermarket," for instance, is just another alienated-consumption song, it leaps instantly to the head of the genre on the empathy of Mick Jones's vocal. And so it goes. Complaints about "slick" production are absurd--Guy Stevens slick?--and insofar as the purity of the guitar attack is impinged upon by brass, pianner, and shuffle, this is an expansion, not a compromise. A gratifyingly loose Joe Strummer makes virtuoso use of his four-note range, and Paul Simonon has obviously been studying his reggae records. Warm, angry, and thoughtful, confident, melodic, and hard-rocking, this is the best double-LP since Exile on Main Street. And it's selling for about $7.50. A+
