The Chicago-based Hudson Shad initially attracted attention for the their immaculate re-creations of scores by the German Comedian Harmonists. Their five voices, and piano (the same composition as that of the Harmonists), have now diversified, to include equally charming and delightful songs such as Gershwin's "Strike Up The Band" and several Weill numbers, including "September Song" and "It Never Was You." Amusing novelties, like "Ali Baba," rely frequently on vocalese for effect; "Four Leaf Clover" is an anecdote from the turn-of-the-century music hall. The Beatles' "Julia" lends itself willingly to Hudson Shad's gorgeous interpretation. Incorporating elements of jazz, classical and an inchoate form of what was soon to become popular music, "Music Box" is a sentimental and beautiful record.
