Albert Luandrew (September 5, 1906* – March 17, 1995), known as Sunnyland Slim, was an American blues pianist who was born in the Mississippi Delta and moved to Chicago, helping to make that city a center of postwar blues. The Chicago broadcaster and writer Studs Terkel said Sunnyland Slim was "a living piece of our folk history, gallantly and eloquently carrying on in the old tradition.

He was born Albert Luandrew in Mississippi and received his early training on a pump organ. After entertaining at juke joints and movie houses in the Delta, Luandrew made Memphis his home base during 1927, playing along Beale Street and hanging out with
the likes of Little Brother Montgomery and Ma Rainey. He adopted his colourful stage name from the title of one of his best-known songs, the mournful "Sunnyland Train." (The downbeat piece immortalized the speed and deadly power of a St. Louis-to-Memphis locomotive that mowed down numerous people unfortunate enough to cross its tracks at the wrong instant.)

Slim moved to Chicago in 1939 and set up shop as an in-demand piano man, playing for a spell with John Lee "Sonny Boy" Williamson before waxing eight sides for RCA Victor in 1947 under the somewhat misleading handle of "Doctor Clayton's Buddy." If it hadn't been for the helpful Slim, Muddy Waters may
not have found his way onto Chess; it was at the pianist's 1947
session for Aristocrat that the Chess brothers made Waters' acquaintance. Slim's Shout Aristocrat (which issued his harrowing "Johnson Machine Gun") was but one of a myriad of labels that Slim recorded for between 1948 and 1956: Hytone, Opera, Chance, Tempo-Tone, Mercury, Apollo, JOB, Regal, Vee-Jay (unissued), Blue Lake, Club 51, and Cobra all cut dates on Slim, whose vocals thundered with the same resonant authority as his 88s. In addition, his distinctive playing enlivened hundreds of sessions by other artists during the same time frame.

In 1960, Slim travelled to Englewood Cliffs, New Jersey, to cut his debut LP for Prestige's Bluesville subsidiary with King Curtis supplying diamond-hard tenor sax breaks on many cuts. The album, Slim's Shout, ranks as one of his finest, with definitive renditions of the pianist's "The Devil Is a Busy Man,""Shake It,""Brownskin Woman," and "It's You Baby."
In the late 1960s, Slim became friends with members of the band Canned Heat and played piano on the track "Turpentine Moan" on their album Boogie with Canned Heat. In turn, members of the band—lead guitarist Henry Vestine, slide guitarist Alan Wilson and bassist Larry Taylor—contributed to Sunnyland Slim's Liberty Records album Slim's Got His Thing Goin' On (1968), which also featured Mick Taylor.
Chicago Jump Like a deep-rooted tree, Sunnyland Slim persevered despite the passing decades. For a time, he helmed his own label, Airway Records. As late as 1985, he made a fine set for the Red Beans logo, Chicago Jump, backed by the same crack combo that
shared the stage with him every Sunday evening at a popular North side club called B.L.U.E.S. for some 12 years.

Finally, after a calamitous fall on the ice coming home from a gig led to numerous complications, Sunnyland Slim died of kidney failure in March 1995. He's sorely missed.
