Fifty cuts by the late great Muddy Waters is a fine choice anytime, because the Chicago singer/songwriter/guitarist remains the pivotal figure in American electric blues. Waters took the sounds of the Delta to the city and never looked back, but he also never forgot where he came from. Anthology 1947-72 traces much of that transition via Muddy’s recordings for Chess Records. There are the classics -- “Good Morning Little School Girl,” “Got My Mojo Working,” “Hoochie Coochie Man,” and “Mannish Boy” -- but lesser-known tunes give the listener deeper insight into this bluesman's power. The plaintive feelings Waters had for his Mississippi homeland come through on “I Feel Like Going Home,” “My Home Is in the Delta,” and “Train Fair Home Blues.” “Stuff You Gotta Watch” and “I’m Ready” capture the sounds of juke joints and South Side Chicago blues clubs of the ‘50s. “Long Distance Call” and “I Just Want to Make Love to You” give insight into Waters as a supreme entertainer. He could laugh and cry in the same tune, his voice and guitar working together as smoothly as the assembly line workers who left their jobs on Fridays and headed to catch Muddy Waters live. Anthology 1947-72 doesn’t replace The Chess Box set of three CDs; it simply streamlines it into two discs, but more important, it’s a reminder that Muddy Waters is hard again, and the virility of his music never falters.
