Little Labels—Big Sound as "blatantly non-commercial", demonstrated to audiences that Chicago Blues could be effectively captured on album. "[O]ne of the first to fully document the smoky ambience of a night at a West side nightspot in the superior acoustics of a recording studio", according to Bill Dahl of
AllMusic, In 1998,
The New York Times described it as among the artist's best-recorded works. In 2008,
The Times declared it to be Wells' "most celebrated album". In their 2005 biography of
Howlin' Wolf, James Segrest and Mark Hoffman make note that it is one of the albums usually cited by critics as "one of the greatest blues albums ever released." ==Track listing==
