At 61 years old, Lucinda Williams has done pretty much everything, but a double album was still on her bucket list. The CD age allowed old-school double albums to fit snugly on 70-minute single albums with room to spare, so Williams worked up these 20 songs (18 originals) and let it fall to 104 minutes, including the 10-minute closer, JJ Cale’s “Magnolia,” that’s worth every second. As befits an artist of her stature, the musicians are a “who’s who” that includes drummer Pete Thomas, Faces keyboardist Ian McLagan and guitarists Bill Frisell and Tony Joe White. Williams uses these experienced farmhands to settle into shuffles, rockers and ballads that she sings in many voices, from warmhearted coo to forceful bandleader to desperate woman in need. The songs are nearly all first-rate, but the slinky/political “West Memphis,” concerning the plight of the West Memphis 3, may be the best of a breathtaking lot. Rob O’Connor
