This week’s Blues Before Sunrise moves through a wide field of blues, jazz, rhythm and blues, gospel, and vocal-group music, with the third hour supplying the program’s central historical focus: an encore presentation of Blues at Chicago’s Furniture Mart. The five-hour sequence does not narrow itself to one sound. Instead, it follows connections among performers, labels, settings, and styles while allowing each hour to establish its own pace.

Hour 1 opens in a jazz-minded, dance-floor-ready setting. Tab Smith’s “Boogie Joogie” sets the first motion, followed by a substantial Cab Calloway sequence that includes “That Man Is Here Again,” “Copper Colored Gal,” “The Hi-De-Ho Miracle Man,” and “Good Sauce from the Gravey Bowl.” Slim & Slam then carry that social, rhythm-centered current through several performances, including “Dopey Joe,” “Sweet Safronia,” “Buck Dance Rhythm,” “Ti-Pi-Tin,” and “Oh Lady Be Good.” Lena Horne, the Delta Rhythm Boys, Meade Lux Lewis, Buck & Bubbles, Spirits of Rhythm, and a return to Tab Smith make the hour a compact survey of varied jazz and vocal settings.

The second hour shifts toward blues and rhythm-and-blues performances while retaining a strong vocal presence. Calvin Boze, Amos Milburn, Charles Brown, Larry Darnell, Helen Humes, Marie Adams, Pigmeat Markham, Christine Kittrell, Jimmy McCracklin, and Sidney Williams make up the first portion. The hour then turns to Ma Rainey before closing with the Original Kings of Harmony, Rev Sundown Jesse McBride, Dorothy Love Coates, and the Soul Stirrers. That closing movement gives the hour a gospel-centered finish without separating it from the blues and R&B currents that came before.

Hour 3 concentrates on recordings made at Chicago’s Furniture Mart, a Chicago landmark built in the 1920s that included a recording studio. Brunswick, Decca, and Vocalion or ARC used the building, whose former 666 North Lake Shore Drive address acquired a reputation that Jazz Record Mart’s Bob Koester associated with superstitious artists. The address later changed to 680 North Lake Shore Drive. The program uses that story as the reason for a rare return to recordings made there, running from Arthur Pettis and Coletha Simpson through Speckled Red, Charlie Jordan, Lorraine Walton, Bessie Mae Smith, and Jesse Clayton.

Hour 4 resumes a broad blues path with Babyface Leroy, Little Walter, Willie Long-Time Smith, John Brim, Memphis Slim, Lonnie Johnson, Tarheel Slim, Sticks McGhee, Buster Brown, Gatemouth Brown, Alex Moore, Robert Shaw, and Robert Pete Williams. The sequence moves among familiar names and less frequently foregrounded performers without forcing them into a single narrow category.

The final hour brings the program toward jazz and late-night blues. Henry Mancini, Duke Ellington, Nat King Cole, Shirly Horn, and Groove Holmes establish the opening stretch before Sister Rosetta Tharpe, T-Bone Walker, Buster Pickens, Lil Son Jackson, Eddie Burns, Ray Agee, and Fleetwood Mac close the five-hour broadcast. “Albatross” provides the final listed selection after Ray Agee’s five-song run, leaving the show with one more change of texture.
