Corky Siegel and the legendary Siegel-Schwall Band return to the Sandwich Opera House stage at 8 p.m. Jan. 19.

Along with the first-wave British Invasion bands such as The Rolling Stones, John Mayall’s Bluesbreakers, and stateside groups such as The Paul Butterfield Blues Band, The Siegel-Schwall Band was instrumental in the Great Blues Revival of the 1960s. Like Paul Butterfield, Siegel-Schwall were Chicago-based, serving as the house band at the famed Pepper’s Lounge. They earned their spurs backing greats like Muddy Waters, Howlin’ Wolf, Little Walter and Willie Dixon.

From 1966 until they disbanded in 1974, they ranked among the most important forces in reaching the baby boomer audience that sustains the blues to this day.
