Silas McClatcher first started singing as a young teen with his identical twin brother, Paul (d. 2006), in Holly Spring, Mississippi. Silas moved to Chicago in 1965, to Milwaukee in 1975, and back to Chicago in 2011, always for better employment opportunities.

One night Milwaukee’s Legendary Bluesman, ‘Stokes’, called Slim up to sing and it was from that point forward his singing became quick in demand, and he received his official blues name “Milwaukee Slim”.

Milwaukee Slim sat in regularly with Stokes and also with Gene and the Soul Gang as they toured all over WI. He has established a rich resume which includes opening shows in WI for Koko Taylor, John Lee Hooker, and Phillip Walker. Milwaukee Slim performed for the Green Bay Packers (2000), and has performed at many WI and IL Festivals over the years, including WI State Fair (1998 – 2004), Shermanfest, and The Chicago Blues Festival. He has been a member of the Midwest Blues All Stars, The House Rockin Blues Review and his own Milwaukee Slim Band. He has performed with the Hayes Family Blues Band, and recorded with Hubert Sumlin, Billy Flynn, Piano Willie, Jim Liban, Barrelhouse Chuck, Calvin Jones, Smokey Smothers, Kent "The Colonel" Knapp, Barefoot Jimmy, Richard Raven, Leroy Airmaster, The Legendary Blues Band, Little Charlie and the Nightcats. and Shoji Naito.
