Most Andrews Sisters compilations focus on the trio's phenomenal run of singles in the late 1930s and early '40s. MUSIC LESSONS WITH THE ANDREWS SISTERS bucks that trend by concentrating on the group's work from the late '40s and early '50s. In this way, MUSIC LESSONS is a unique collection, offering up 25 tracks of lesser-known, yet thoroughly excellent material. Though the Sisters' post-war period was less remarkable commercially, their tight, intricate harmonies never lost any of their luster. Patty Andrews gets a couple of solo spots, and guest appearances by Bing Crosby and Red Foley mix things up a bit. Improved sound, and the fact that many of these tracks are appearing on CD for the first time, make this a special package for collectors and casual fans alike.
