RESTOCK. Eponymous albums are usually either debuts or the work of musicians trying to introduce themselves to a new audience. Count Liz Phair among the latter. It's Phair's fourth studio album, but her first since 1998, and it's a long way from the arty, low-fi sound that marked her true full-length debut, 1993's Exile in Guyville. Phair has developed into a considerably more confident singer, while her songs and the production they receive here are as slick and radio-friendly as anything by, say, Avril Lavigne. That's no surprise, since Lavigne's production team, the Matrix, produced many of the tracks here. (The rest are helmed by LA rock stalwarts Michael Penn and Pete Yorn producer R. Walt Vincent.)
